Update MATLAB's MKL
Intel's current MKL version is 11.3.1, while MATLAB uses version 11.1.1. If you would like to use the latest version with MATLAB, you can use the batch script to automate the process. To execute via cmd.exe on Windows, the text commands are
cd "C:\Program Files (x86)\Intel\Composer XE 2015\mkl\bin\"
@call mklvars.bat intel64 && set BLAS_VERSION=mkl_rt.dll && set LAPACK_VERSION=mkl_rt.dll
"C:\Program Files\MATLAB\R2014b\bin\matlab.exe"
You may need to modify the program locations. If you start MATLAB via it's usual start menu shortcut, MATLAB will use the version of MKL that it shipped with. Thus you can use both the default MKL version (by starting MATLAB like you're used to) or the current MKL version with the cmd script. To verify your MKL version, type "version -blas" and "version -lapack" in MATLAB.
In my tests, 11.3.1 speeds up MATLAB's BLAS routines by about 20%.

Thanks for your script, does anyone know how to do this in Linux?
thanks for update, I encountered the problem of using "tf" (Not enough storage is available to complete this operation.), but this update fixed this error. thx a lot.
Thank you very much for the code. I have another question: Is it possible to control the Conditional Numerical Reproducibility (CNR)? I tried it and added the following, which did not work out (still set to AVX2)...
&& set MKL_CBWR = SSE2
Thanks!
Today it should be like this:
cd "C:\Program Files (x86)\IntelSWTools\parallel_studio_xe_2016.1.051\compilers_and_libraries_2016\windows\mkl\bin"
@call mklvars.bat intel64 && set BLAS_VERSION=mkl_rt.dll && set LAPACK_VERSION=mkl_rt.dll
"C:\Program Files\MATLAB\R2015b\bin\matlab.exe"
This script is limited to a one time run. If you were to start Matlab with this script, close Matlab, and then start Matlab normally, Matlab will use it's original MKL.
Is this script create a new system wide variable or is it limited to the one time I run it and when I close it all disappear?
Thank You.
