What error message do you get, when you run the following command ?
mex -v setup
Could you please copy-paste the complete error message from MATLAB ?

Hi Advait
By looking at the output from "mex -v -setup", the issue is caused by the Windows registry entry not pointing to the correct installation folder. Since we have stopped relying on the registry entry from Visual Studio 2019, we should not see such issues with VS 2019 and later versions of VS.
To resolve this issue for Visual Studio 2017 Professional, please reinstall (following the install instructions) in "C:\Program Files (x86)\Microsoft Visual Studio\2017" and run "mex -v -setup" in MATLAB.

Installing VS fully instead of only the build tools might help, it did for me:
Be sure to install the whole Visual Studio program, not only the build tools (MSVC v142 - VS 2019 C++), as otherwise MATLAB can't find it.
Tried getting MSVC v142 - VS 2019 C++ to work with MATLAB R2021a, running the following:
mex -setup -v C++
Resulted in:
Did not find installed compiler 'Microsoft Visual C++ 2019'.
After uninstalling MATLAB and VS Build Tools 2019, and installing MATLAB again and VS 2019 fully, not only the build tools, it worked out.

I had a similar problem where MATLAB couldn't find MSVC C++ v141, 142 or 143 (I installed all 3 to see if it would fix the problem) and I did not want to install the full build tools.
I found that after installing the Windows SDK component, MATLAB could find the installed compilers. I attached an image of the components that I have installed.
I need some components for other purposes, but for MATLAB you at least need:
- MSVC C++ build tools
- Windows 10/11 SDK
