Upon trying to compile a file using mex, I receive the following error message:

Error using mex

No supported compiler was found.

I installed Visual Studio 2017 with support for C++ and actually

mex -setup C++

lets me choose my compiler.

Which additional diagnostics could I run in order to pin down the problem?

You would run

mex -setup C++

This lists a couple of options in case it finds a suitable compiler like the following:

mex -setup:'C:\Program Files\MATLAB\R2020b\bin\win64\mexopts\msvcpp2015.xml' C++

By the way, Visual Studio does not install the C compiler by default.

If you just run

>> mex -setup

it should present you with the compilers that Matlab can actually see. That should provide a clue.

mex -v -setup

can help diagonse problems.
