## How to determine the version of MKL being used by MATLAB

April 25th, 2012 | Categories: math software, matlab | Tags:

MATLAB uses the Intel Math Kernel Library (MKL) behind the scenes to perform many linear algebra operations. I wondered what version of the MKL was being used by MATLAB 2012a on my 64 bit Windows machine. The most straightforward way to determine this is to simply ask MATLAB:

>> version -lapack
ans =
Intel(R) Math Kernel Library Version 10.3.5 Product Build 20110720 for Intel(R) 64 architecture applications
Linear Algebra PACKage Version 3.3.1

>> version -blas
ans =
Intel(R) Math Kernel Library Version 10.3.5 Product Build 20110720 for Intel(R) 64 architecture applications
