Variables with more than 2^32-1 elements. Warning: The MATLAB C and Fortran API has changed to support MATLAB MEX configured to use 'MinGW64 Compiler (C)' for C language compilation. Mex generation of C code works smoothly, but when I tried to select g-fortran I get this > mex -setup Therefore I manually installed the same version (but with gfortran) and changed the environment variables accordingly. Is there any work-around for this? I initially installed MinGW as official add-on of matlab, but I noticed that this specifically release does not contain gfortran. Officially this Matlab release in windows only supports Intel's commercial Fortran compiler ifor.

F file needs to be preprocessed to generate. I have a simple example fortran code, 'timestwo.f'. Does anyone know how to bypass the limitation of matlab in selecting Intel's compiler and force it to use gfortran instead? Instead, MATLAB displays the appropriate mex command syntax forĬhanging the default compiler.I'd like to compile fortran code in Matlab 2017b, Win10, to get a mex-file.
