Please try the following steps to resolve this issue.
1. Download MinGW 6.3:
2. Extract the ZIP-file in an empty directory. Ensure that there are no spaces in the path, for example: C:\MinGW-64
3. Please create the environment variable MW_MINGW64_LOC like you can find here:, which points to the path mentioned in 2, for example:
4. Please restart MATLAB and then call 'mex -setup' in MATLAB in order to check and configure MinGW. The output should show something like: "MEX configured to use 'MinGW64 Compiler (C)'...".
Hope this helps.
