Demonstrate that Matlab MEX C / C++ compiler wrapper is working on your system with the following commands. Ensure you are using a supported compiler with Matlab as the supported compilers are distinct across operating systems. These commands are all from within Matlab.

Setup Matlab C / C++ compiler

Setup Matlab with C and C++ compilers by:

mex -setup -v

mex -setup -v C++

Verify configuration by:

mex.getCompilerConfigurations('C')

mex.getCompilerConfigurations('C++')

Example C MEX

1. Copy the Matlab example code:

   copyfile(fullfile(matlabroot,'extern','examples','mex','yprime.c'), pwd)
   

2. compile

   mex yprime.c
   

3. use the compiled code

   yprime(3,[4,2,7,1])
   

   which returns

   ans = 2.0000 5.9924 1.0000 2.986

Notes

if you get missing compiler errors, do MEX troubleshooting
