September 2nd, 2012

Welcome to the August edition of A Month of Math Software– a regular series of articles where I share what’s shiny and new in the world of mathematical software.  If you like what you see and want more, take a browse through the archives.  If you have some news that you think should go into next month’s edition, contact me to tell me all about it so I can tell the world.

This edition includes lots of new releases, blog posts and news about mathematics on mobile devices…enjoy!

Mobile Mathematics

August was a very big month for mobile mathematical applications with the following releases

General purpose mathematics

Do numerical computing using….Javascript!

  • The Numeric Javascript library has been updated to version 1.2.2. The main new feature is linear programming– the function is numeric.solveLP()

Mathematical software libraries

GPU Programming

GPU stands for Graphical Processing Unit but these days you can get a GPU to do a lot more than just graphics.  You could think of them as essentially massively parallel math  co-processors that can make light work of certain operations.

  • Jacket is a commercial GPU Processing add-on for MATLAB.  In recent blog posts, the Jacket developers discuss SAR Image Formation Algorithms on the GPU and Option Pricing.
  • CULA is a set of commercial GPU-accelerated linear algebra libraries.  CULA-Dense is, as you might expect, for dense matrices and is now at version 15.    CULA-Sparse is at version S3.  I can’t find a what’s new document but the main change seems to be the addition of support for NVIDIA’s Kepler architecture.  The CULA library can be called from C, C++, Fortran, MATLAB, and Python and is free for individual academic use.
  • GPULib is a commercial software library enabling GPU-accelerated calculations for IDL.  In a recent blog post, one of GPULib’s developers has been experimenting with OpenCL support.

Statistics

Academic codes and applications

  • Version 3.0 of the SCIP Optimization Suite has been released. According to the website, ‘SCIP is currently one of the fastest non-commercial mixed integer programming (MIP) solvers. It is also a framework for constraint integer programming and branch-cut-and-price’. Here are the all important Release Notes and Changelog.
  • Templates for First-Order Conic Solvers (TFOCS, pronounced tee-fox) is a software package that provides a set of templates, or building blocks, that can be used to construct efficient, customized solvers for a variety of models.  The latest version, 1.1a, was released back in February but I have only recently learned of it and so am including it in this month’s edition.  A set of demos and wiki for this software is available.
  • Version 1.0 of Blaze has been released.  Blaze is an open-source, high-performance C++ math library for dense and sparse arithmetic.  There is a getting started tutorial and a set of benchmarks.
August 5th, 2012

Welcome to the slightly delayed July 2012 edition of A Month of Math Software where I take a look at recent events in the world of commercial and open source mathematical software. Feel free to contact me if you have news that you’d like including in next month’s edition.

Mark 23 of the NAG Toolbox for MATLAB

The latest version of my favourite MATLAB Toolbox has been released. Mark 23 of the NAG (Numerical Algorithms Group) Toolbox for MATLAB includes lots of new stuff in areas such as global optimisation, wavelet transforms, option pricing formulae, weighted nearest correlation matrices, curve and surface fitting and loads more.  NAG have also thrown in a lot of usability improvements for good measure.

The NAG Toolbox for MATLAB is essentially a MATLAB interface to NAG’s highly regarded Fortran library and contains over 1500 numerical routines.   My employer, The University of Manchester, has a full site license for the NAG Toolbox along with several other NAG products and they are used a lot.

I’ve written about old versions of the NAG toolbox several times including:

Spreadsheets that aren’t Excel

General purpose mathematics

  • Version 5.2 of Sage was released on 25th July. Sage is one of the best open-source mathematical packages available and is based on Python.  See what’s new by reading the release annoucement.  Earlier this month, I reported on a new interactive mathematics website based on Sage.
  • Smath Studio is a superb free clone of PTC’s Mathcad and it’s recently been updated to verision 0.95.4594.   One exciting piece of news is that the developer is working on an Android version!
  • Numeric Javascript is now at version 1.1.8.  There is probably new stuff but I have no idea what it is as I can’t find a changelog.  Looks good though!
  • Version 17 of the free Euler Math Toolbox is now available with previews of version 18 already in the works (below).

Euler Math Toolbox

Python

  • Version 0.8.1 of pandas, The Python Data Analysis Library, has been released.  See what’s new at http://pandas.pydata.org/pandas-docs/stable/whatsnew.html
  • A release candidate for SciPy 0.11 is now available and includes lots of neat stuff.  The optimisation section seems to have had a major overhaul for example.  Note that this is not the final release of 0.11 and so some bugs may be lingering.
June 30th, 2012

Welcome to the June 2012 edition of A Month of Math Software.  The archive to all previous editions is here.  Feel free to contact me if you have news that you’d like including in next month’s edition.

A list of packages based upon SuiteSparse

  • Tim Davis has put together a list of projects and packages that rely on the various sparse matrix codes he’s written or co-authored over the years (UMFPACK, CHOLMOD, SuiteSparseQR, KLU, CSparse, and the ordering codes AMD and COLAMD).  The list is very impressive but is incomplete.  Drop Tim a line if you work on a project that uses his codes.

Python based software

  • Sage, the superb computer algebra system based on Python and dozens of other open source projects, has seen a minor update to 5.0.1.  Take a look at the changelog for the new stuff.
  • Pandas, the Python Data Analysis Library, is now at release 0.8.0.  This is a major update on the old 0.7.3 and has significantly improved timeseries data analysis in pandas.

Try a spreadsheet that isn’t Excel

  • Gnumeric, the free spreadsheet that’s part of the GNOME office suite, was updated to 1.11.4 in June.  Find out what’s new here.
  • A new version of LibreOffice (version 3.5.4) was released at the end of May but I missed it in May’s update.  LibreOffice is the fork of OpenOffice that everyone should be using these days and includes a great spreadsheet program.

Math-o-mir – The mathematical notepad

  • Danijel gorupec contacted me to tell me of a new release of his free software, Math-o-mir.  According to Danijel ‘The Math-o-mir is a software tool designed to write and edit mathematical equations as easily as possible. The goal was to achieve the same level of simplicity as with pencil and a sheet of paper. It is designed to act as your personal math notepad where you can write down your quick and informal calculations.’  I haven’t had chance to try it myself but it looks interesting.  See what’s new in the 1.7 release over at Danijel’s blog.

Gnu Regression, Econometrics and Time-series Library

Numerical Libraries

Blogs, Bits and Bobs

  • Planet Octave is now up and running.  This is a collection of blogs related to Octave and is currently made up of posts from the Google Summer of Code students. Some great stuff on the Just in Time (JIT) compiler development, Octave GUI and more.
  • PTC’s MathCAD blog turns 3 years old. Head over and take a look at their 5 most popular posts.  If you can’t afford Mathcad, why not try the free Mathcad clone, SMath Studio which saw a new release this month.
  • Geogebra now has a blog.  The June newsletter is also worth checking out.  Wikipedia tells us that ‘GeoGebra is an interactive geometry, algebra, and calculus application, intended for teachers and students.’
  • Version 0.97 of Eureqa/Formulize has been released.  If you don’t know what this is, take a look at the video.  In a nutshell, you plug in data and it figures out the formula that best models it.

Mathematical libraries

  • The Numerical Algorithms Group (NAG) released a new version of the commercial NAG Library for SMP and multicore.  This is a version of their Fortran library which includes a few hundred routines that have been optimised for multicore processors.  The latest release, Mark 23, adds an extra 116 routines (some of them have been written up in detail) bringing the total number of functions to 1704. A total of 337 have been parallelised to make use of multicore processors.  I played with this library when it was at Mark 22.
  • Version 1.2 of Magma, the linear algebra library for NVIDIA GPUs has been released. The OpenCL version, clMAGMA has also seen an update in version 0.2.

General Purpose Mathematics

  • Version 5.0 of Sage was released on 14th May; go to the changelog to see what’s new.  Sage is a superb free alternative to Mathematica, Maple or MATLAB based on the Python programming language and over 100 other open source projects.  If you’ve never heard of Sage, these Videos serve as a good introduction.
  • Version 5.27 of Maxima has been released.  Maxima is a free computer algebra system that’s available for all major operating systems and it is very capable.  Features include symbolic calculus, linear algebra, plotting and arbitrary precision arithmetic.  There is a post here on Walking Randomly on how to use it to plot direction fields for 1st order ODEs.

April 2nd, 2012

Welcome to this month’s MMS which includes the usual mix of commercial and open source software spanning across multiple disciplines.  Last month’s edition is here and the archive of all previous editions is at http://www.walkingrandomly.com/?cat=47.  Thanks so much for all of the contributors this month without whom these articles would be significantly more difficult to write.  As always, if you have some mathematical software news then feel free to contact me.

General purpose commercial packages

  • Maple 16 was released in March and according to Maplesoft it has over 4500 additions and improvements compared to the previous version.  Maple is very strong in polynomial arithmetic and Maplesoft have released benchmarks showing how Maple 16 is hundreds of times faster than Mathematica 8 in this area.  For example, multiplication of two dense polynomials in 3 variables, each of degree 30 takes 110 seconds in Mathematica 8 but only 0.52 seconds in Maple 16 according to these new benchmarks.
  • MATLAB version 2012a was also released in March with the usual batch of improvements and updates.  One of the highlights for me is the fact that The Mathworks now offer the MATLAB Compiler Runtime for free download, significantly simplifying the deployment of compiled applications.
  • Version 2.18-5 of Magma, the commerical computer algebra system specializing in number theory, has been released.  Click here for the v2.18-5 changelog

Mathematical Open Source and Freeware

  • The Python Data Analysis library, pandas, is designed to help Python programmers perform in depth data analysis projects without having to resort to R.  Version 0.7.2 was released in March and you can see what’s new at http://pandas.pydata.org/pandas-docs/dev/whatsnew.html.  Thanks to Tom Brander for the heads up on this one.

Vital statistics

Finite Differences and Elements

  • “The Chombo software package provides a set of tools for implementing finite difference methods for the solution of partial differential equations on block-structured adaptively refined rectangular grids with embedded boundaries. Both elliptic and time-dependent modules are included. Support for parallel platforms and standardized self-describing file formats are included.”  Version 3.1 was released in March…get it at https://commons.lbl.gov/display/chombo/Chombo+Download+Page
  • The FEniCS book has been published and is available online and in print. The online version is available at http://dx.doi.org/10.1007/978-3-642-23099-8 and hard copies can be ordered from Springer (http://tinyurl.com/3ueq9hk) or book sellers.  The FEniCS Project is a collection of free software with an extensive list of features for automated, efficient solution of differential equations.

Eigenvalues everywhere

The following two packages were recently announced on the Numerical Analysis Digest.

  • “The FEAST solver package is a free high-performance numerical library for solving the standard or generalized eigenvalue problem, and obtaining all the eigenvalues and eigenvectors within a given search interval.  The FEAST algorithm takes its inspiration from the density-matrix representation and contour integration technique in quantum mechanics.”  Download version 2.0 from http://www.ecs.umass.edu/~polizzi/feast/download.htm
  • “ELPA” is a new direct eigensolver library that addresses scalability and performance, especially for parallel applications. ELPA builds on the ScaLAPACK type interfaces that are often used in existing implementations, but key parts of the eigenvalue solution are then replaced with ELPA’s own routines in an easy-to-use way. The library is particularly useful when a substantial part of all eigenvalue / eigenvector pairs is needed. Released under an LGPL-like license, ELPA has been successfully tested for matrix sizes up to 680,000 and with up to 294,000 CPU cores on a BlueGene/P system.”  A hybrid version (OpemMP and MPI) was released in March. http://elpa.rzg.mpg.de/

March 2nd, 2012

Welcome to the latest edition of A Month of Math Software which includes information on a new language for scientific computing, statistics software education in New Zealand as well as the usual mix of mathematical and scientific software releases from the worlds of commercial and free software.

If you’d like something added to next month’s edition then contact me (it’s free).  If you want to see old editions then take a look at the MMS archive.

A new language for scientific computing

Learn statistics with the free GenStat for teaching and Learning (GTL)

Mathcad Prime

  • Mathcad Prime 2.0 has been released and has lots of new improvements.  I’ve never been a fan of Mathcad and Prime 1.0 was a big disappointment for me but many people seem to like it.  Let me know if you are one of them.

Attack of the clones

  • A major new release of the free MATLAB clone, Octave, has is now available.  Version 3.6.1 has lots of new goodies and you can read all about them in the 3.6.1 NEWS file.
  • Version 13.7 of the MATLAB-like Euler Math Toolbox is now available.  See the change log for the improvements.
  • Version 0.92 of the popular Mathcad clone, Smath studio, was released in February.

Number theory

  • A new version of PARI/GP is now available for download.  From the software’s website: “PARI/GP is a widely used computer algebra system designed for fast computations in number theory (factorizations, algebraic number theory, elliptic curves…), but also contains a large number of other useful functions to compute with mathematical entities such as matrices, polynomials, power series, algebraic numbers etc., and a lot of transcendental functions.”  Head over to the changelog to see what’s new.

Perl and Python

  • If you like to work with the Perl programming language then you should take a look at the Perl Data Language (PDL).  A new version was released in February– version 2.4.10– which includes automatic multi-thread support among other things.
  • If you prefer Python, you’ll probably like to know that version 0.10.1 of scipy, the scientific library for python, has been released.

Math software on tablets

  • The Mathematica kernel is now running on iPad!
  • GeoGebra is a superb piece of free software for mathematics learning and teaching.  Thanks to the release of the beta version of GeoGebraWeb, you can now experience some of the GeogGebra goodness on Tablets and Chromebooks.  This forum post gives the details.

Finite Elements

  • February saw the release of two new C++ libraries: ViennaMath and ViennaFEM.  The author of the libraries writes “The symbolic math kernel library ViennaMath (http://viennamath.sourceforge.net/) written in C++ allows for both runtime and compiletime evaluation, differentiation, integration, and substitution of simple mathematical expressions. In short, ViennaMath offers some of the advantages of full-fledged computer algebra systems such as Mathematica or Maple directly within C++. The symbolic math kernel is intended to be used for numerical applications and is included in the new finite element library ViennaFEM (http://viennafem.sourceforge.net/), which allows for the specification of either the strong or the weak formulation of the underlying PDE directly in code. Even though ViennaFEM is still in alpha-state, the first release already supports grids in 1d, 2d (triangular,quadrilateral) and 3d (tetrahedral, hexahedral).”

February 4th, 2012

Welcome to the first MMS of 2012.  This series has been going for a year now and I’m very pleased to say that it’s become quite popular.  In the beginning I had to trawl the web for all of the news I featured here but a sizeable percentage of it gets sent to me these days.  If you’ve got some news about mathematical sofware then contact me and tell me all about it.

General purpose mathematics

  • Sage, the python based open source computational algebra system, has been updated to version 4.8.  View the changelog to see what’s new.  94 people contributed to this release according to the changelog which is very impressive!  I wonder how that compares to the number of developers on commercial systems such as Maple, Mathematica and MATLAB?
  • After a long wait, we get not one but two new versions of the free Mathcad clone, Smath Studio in one month.  Lots of great new features in versions 0.90 and 0.91 of this very nice multiplatform application.
  • Verision 2.18-3 of Magma, the commercial computational algebra system, has been released.

Community

  • The new Mathematica StackExchange site has been launched so head over there for all of your Mathematica question and answer needs.
  • The Mathworks have released an online community programing game for MATLABers called Cody.  Problems start off incredibily easy and as you solve them, more difficult ones get unlocked.  Your attempts are automatically scored by The Mathwork’s servers so feeback is instant and you can view other people’s solutions once you’ve solved a problem yourself.  All in all, a great new way to sharpen your MATLAB programming skills.

Partial Differential Equations

  • A new set of open-source software tools written in C++ for performing Partial Differential Equation (PDE) analysis and solving PDE constrained optimization problems has been released – Stanford University Unstructured (SU2)

Mobile

  • An article on smartphone apps for mathematics, written by Peter Rowlett, Hazel Lewis and I, has been published in the January 2012 edition of Mathematics Teaching.  Ironically, none of the authors of the article have seen the finished product yet since we are not subscribers!
  • Michael Carreno sent me news of the release of his graphical calculator app for iPhone, AbleMath.  I haven’t had chance to try it yet since Mrs WalkingRandomly refuses anything mathematical on her iPhone and I am an Android man myself.  However, the screenshots look very nice and, since it’s free, it’s a lot cheaper than those expensive, underpowered junkers that American schools seem to insist on teaching with.

AbleMath
Linear Algebra

Linear Algebra

  • Version 3.0 of the NLEVP (Nonlinear Eigenvalue Problems) Toolbox for MATLAB was released in December 2011 but I found out about it too late for December’s edition of MMS.  It contains problems from models of real-life applications as well as problems constructed specifically to have particular properties. The collection is fully documented in the Technical Report and user’s guide.  This release contains 52 problems (up from 46 in version 2.0) and new functionality; it is also now compatible with GNU Octave.
  • ViennaCL, a GPU-accelerated C++ open-source linear algebra library, was updated to version 1.2.0 on December 31st (just missing the deadline for December’s Month of Math Software).  Roughly speaking, ViennaCL is a mixture of Boost.ublas (high-level interface) and MAGMA (GPU-support), yet based on OpenCL rather than CUDA.

Welcome to the final Month of Math Software for 2011.  Lots of people sent in news items this month so hopefully there will be something of interest to everyone.  If you have any news items or articles that you think will fit in to next month’s edition then please contact me and tell me all about it.

If you like what you see and want more then check out the archives.

Mathematica StackExchange Proposal

There is a proposal to launch a new Mathematica-specific questions/answers site on StackExchange.  All it needs is enough interested people who will follow or commit to the proposal. There is already a vibrant Mathematica community on StackOverflow, where many of the MathGroup regulars participate.  Unfortunately not all questions are on topic or tolerated there, so many believe that it would be better to launch a new site.  If you are willing to lend support to this proposal then add your name to the list at  http://area51.stackexchange.com/proposals/37304/mathematica?referrer=23yK9sXkBPQIDM_9uBjtlA2

General mathematical software

Making MATLAB faster

More mathematics in CUDA

  • Release candidate 2 of version 4.1 of NVIDIA’s CUDA Toolkit has been released.  There’s lots of interesting new mathmatical functions and enhancements over version 4.0 including Bessel functions, a new cuSPARSE tri-diagonal solver, new random number generators (MRG32k3a and MTGP11213 Mersenne Twister), and one thousand image processing functions!

Differential Equations

  • Fenics mesh

Libraries

  • The HSL Mathematical Software Library (http://www.hsl.rl.ac.uk) is a high performance Fortran library that specialises in sparse linear algebra and is widely used by engineering and optimization communities. Since the release of HSL 2011 at the start of Feburary, there have been a number of updates to the library.  Take a look at http://www.hsl.rl.ac.uk/changes.html for the detailed list of changes.  Interestingly, this library is free for academic use!
  • FLINT (Fast Library for Number Theory) version 2.3alpha has been released.  I can’t find any info on what’s new at the moment.
  • Version 5.1 of AMDs linear algebra library, ACML, is now available.
  • Version 1.6 of the AMD Accelerated Parallel Processing Math Libraries (APPML) has been released.  I’m not sure what’s new since the release notes only contain information about Timeout Detection and Recovery rather than info on the new stuff.  AMD Accelerated Parallel Processing Math Libraries are software libraries containing FFT and BLAS functions written in OpenCL and designed to run on AMD GPUs. The libraries also support running on CPU devices to facilitate debugging and multicore programming.
  • Version 2.4.5 of PLASMA (Parallel Linear Algebra for Scalable Multi-core Architectures) was released back in November but I somehow missed it.  Check out the 2.4.5 release notes for details.
