I have installed matlab R2021a, CUDA 11.2, and visual studio 2022 community with MSVC v140 -Vs2015 C++ build tools (v14.00). But when I run "mex -setup " in matlab, I got the following error messages
>> mex -setup
Error using mex
Supported compiler not found. You can install the freely available MinGW-w64 C/C++ compiler; see Install MinGW-w64 Compiler. For more options, visit

If I run "mex -setup -v C++ " in matlab, I got the following messages.
>> mex -setup -v C++
Verbose mode is on.

Using a 2022 compiler with a 2021 MATLAB isn't a supported workflow. Can you upgrade MATLAB?
