Hello!

I am trying to deal with the GPU coder to generate the CUDA code for a simple example of matrix multiplication. The first problem i encountered was the absence of the compiler. i used the mex -setup function and matlab did not find any compilers. i have installed the MinGw using the guide descrined in https://www.mathworks.com/matlabcentral/answers/313298-i-already-have-mingw-on-my-computer-how-do-i-configure-it-to-work-with-matlab?s_tid=ans_recom_leaf and i could generate CPU code using the GPU coder. However. when i tried to generate the GPU code i got this error "Warning: Selected MEX compiler 'MinGW64 Compiler (C++)' is not supported for GPU code generation. Refer to the GPU Coder documentation for a list of supported GPU MEX compilers. ". I have installed the Visual C++ 2015-2022 and Visual Studio Community 2022 but matlab does not see this compilter when using the mex -setup and mex -v -setup functions. Moreover, it does not also see the MinGw compilter so i set the path manually. Can anyone give me a hint or suggestions how to connect matlab with Visual C++ compiler? Matlab version is 2023a and CUDA toolkit version is 11.8

The link you followed for installing the mingw compiler is obsolete. You should use the Add-On Manager to install the proper mingw compiler for your version of MATLAB. https://www.mathworks.com/help/matlab/matlab_external/install-mingw-support-package.html
