Hi everyboy,
I am trying to compile a Fortran code (f90) using "MEX" command.
  • This is my MATLAB version: R2012b;
  • This is my compiler: Intel Visual Fortran 12 (with Microsoft Software Development Kit (SDK) linker);
and (unfortunately) this is the only result I've obtained:

Does anybody know how to fix it?
Thanks in advice!

Paolo: You simply need to replace mxIsString with mxIsChar and mxCreateScalarDouble with mxCreateDoubleScalar. Check the documentation to make sure the right syntax is used in your code.
