Unable to setup mex for Intel Fortran Compiler

I have been trying to set up the Intel Fortran Compiler to work on MATLAB R2019a for Windows. I have been able to confirm that the Compiler is working well on the Visual Studio 2019. However, running mex -setup on the MATLAB Command Window, the program cannot find the compiler. I have attached the error message below.

```

I would appreciate any advice on how to get the mex to work. Thanks!

Notes for the Windows family

3. Intel compilers require that Microsoft Visual Studio 2015 or 2017 also be installed on your system.

That is a problem for you because you have VS 2019 installed.

Thank you for the advice! I was able to setup the Compiler.
