A Month of Math Software – February 2013

March 4th, 2013 | Categories: math software, Month of Math Software | Tags:

Welcome to the latest Month of Math Software here at WalkingRandomly.  If you have any mathematical software news or blogposts that you’d like to share with a larger audience, feel free to contact me.  Thanks to everyone who contributed news items this month, I couldn’t do it without you.

The NAG Library for Java

MATLAB-a-likes

  • Version 3.6.4 of Octave, the free, open-source MATLAB clone has been released.  This version contains some minor bug fixes.  To see everything that’s new since version 3.6, take a look at the NEWS file.  If you like MATLAB syntax but don’t like the price, Octave may well be for you.
  • The frequently updated Euler Math Toolbox is now at version 20.98 with a full list of changes in the log.  Scanning through the recent changes log, I came across the very nice iteratefunction which works as follows
    >iterate("cos(x)",1,100,till="abs(cos(x)-x)<0.001")

Mathematical and Scientific Python

  • The Python based computer algebra system, SAGE, has been updated to version 5.7.  The full list of changes is at http://www.sagemath.org/mirror/src/changelogs/sage-5.7.txt
  • Numpy is the fundamental Python package required for numerical computing with Python.  Numpy is now at version 1.7 and you can see what’s new by taking a look at the release notes

Spreadsheet news

R and stuff

This and that

  • The commercial computer algebra system, Magma, has seen another incremental update in version 2.19-3.
  • The NCAR Command Language was updated to version 6.1.2.
  • IDL was updated to version 8.2.2.  Since I’m currenty obsessed with random number generators, I’ll point out that in this release IDL finally moves away from an old Numerical Recipies generator and now uses the Mersenne Twister like almost everybody else.

    If you’re interested in test the bleeding edge GNU Octave (3.7.2+ with GUI), this is a installer for Windows: http://dl.dropbox.com/u/45539519/octave-3.7.2%2B-vs2010-setup.exe

    Please set the font of the terminal if the cursor seems strange. Lucida Console is a good choice.

    Best,
    Júlio.

    There’s actually a much newer version of Magma that was released today: http://magma.maths.usyd.edu.au/magma/releasenotes/2/19/4/

    :)

    Full disclosure: I know one of the core maintainers.
