I downloaded the suggested app (cannot honestly remember the name) and then in the command window i typed:
mex -setup
mex -setup C
but still it keeps on giving the the error:
A C/C++ compiler has not been selected with mex -setup
Any suggestions?

Hi,
This can be because of the reason that you don't have a compiler installed on your system.
So, first you need to install the compiler.
To install the MinGW-w64 compiler, use the Add-Ons menu.
  • On the MATLAB Home tab, in the Environment section, click Add-Ons > Get Add-Ons.
  • Search for MinGW or select from Features.
If you only have the MinGW compiler installed on your system, the "mex" command automatically chooses MinGW. Go to the next step. However, if you have multiple C or C++ compilers, use the below command to choose MinGW.
mex -setup
Also, it might be possible that you already have a compiler installed, but it's installation path might not be correct, so you can also have a look at the same.
Now you can build the MEX files, like:
mex myProgram.c
Hope it helps!
