MEX compiler 'Intel Parallel Studio XE 2019 for C++ with Microsoft Visual Studio 2017' is not supported.

I cannot compile MEX code on Matlab 2019a (9.6.0.1150989) using Intel Parallel Studio 2019. I get this error:

The current MEX compiler 'Intel Parallel Studio XE 2019 for C++ with Microsoft Visual Studio 2017' is not supported.

While here it says it is supported!

This is the file I am trying to build in Matlab Coder:

function x=test()

x=zeros(10,1);

for i=1:10
    
    x(i)=i*(5+i);
    
end

end

Are you trying to do anything beyond using mex? That combination should be supported for mex but not for anything else.

@walteer Roberson

No just tried to build a simple code in Matlab coder by selecting MEX.

As suggested in the link (https://www.mathworks.com/support/requirements/supported-compilers.html), Intel Parallel Studio XE 2019 for C/C++ is not supported by MATLAB Coder in R2019a.

[Walter Roberson]

Right, you can use the mex command to build C++ source, but next to nothing else with with that combination.

OK, now I get it! So it is not supported inside MATLAB Coder app but supported for MEX compilation.

So how can I compile the generated MEX code from MATLAB Coder using Intel Parallel Studio and MEX command?

"I want to build a mex to use multithreading"

Are you following the flow suggested at https://www.mathworks.com/help/coder/ug/acceleration-of-matlab-algorithms-using-parallel-for-loops-parfor.html ?

The supported compilers list https://www.mathworks.com/support/requirements/supported-compilers.html for R2019a has footnote 6 for compilers that do not support OpenMP. The four compilers supported by MATLAB Coder are MinGW 6.3 C/C++; Microsoft Visual C++ 2017 product family; Microsoft Visual C++ 2015 Professional (**not** Community edition); and lcc-win64 . The lcc-win64 compiler is the only one that has the footnote about no support for OpenMP.

Sufficiently old Visual Studio products did not support OpenMP, but more current releases do.

Using the method you mentioned MATLAB crashes when I run the MEX code!

MATLAB Coder compiles the code for you, unless you select generate code only.

Is there any specific reason you want to use mex command to compile the genereated code?
