Configuring a MEX compiler in MATLAB

• List of compatible C compilers: http://www.mathworks.com/support/compilers/R2016a/index.html

Windows

• You can try with following the instructions here. Several things can go wrong; see here for some troubleshooting.
  • Great. If you have MATLAB 2015a and Windows 10, compiling MEX files might be just not possible. MATLAB 2015b and successive versions should work. See thread here.
• As an alternative, if you already have a C compiler that you want MATLAB to recognize, download this script provided by Bas van Opheusden and follow his instructions: "After downloading this file, move it to *C:\Users\yourusername\AppData\Roaming\MathWorks\MATLAB\yourmatlabversion*. This folder is hidden but it does exist. Then you'll need to edit the name of the compiler and its path in the mexopts.bat script (lines 5,7, and 13)."

Mac OS X

• Install Command Line Tools: In Terminal, enter xcode-select --install and install.
• Configure MATLAB:
  • In MATLAB, enter mex -setup to see if MEX is configured.
  • If it is not, enter edit ([matlabroot '/bin/maci64/mexopts/clang++_maci64.xml']). If you are running MacOS 10.11, find and replace all instances of '10.10' with '10.11'. Presumably, you should be able to do this in MacOS 10.12 as well.
  • Enter edit ([matlabroot '/bin/maci64/mexopts/clang_maci64.xml']) and do the same.
  • Now, restart MATLAB, and try mex -setup again. It should indicate that it's properly configured.
