However, if Matlab doesn’t detect your compiler location, you may get an error like
Error in loadlibrary>getLoadLibraryCompilerConfiguration
Which can be fixed by telling Matlab your compiler path via Windows environment variable
MW_MINGW_LOC by typing in Matlab (assuming you installed your compiler under
