The FORTRAN MEX example in the documentation appears to not work. I am trying to run this command on the yprimef.F and yrprimefg.F files that are present in:
$matlabroot\extern\examples\mex
where matlabroot is the MATLAB installation directory.
I run the following command to create a MEX-file on a 64-bit Linux machine using the supported compiler:
mex yprimef.F yprimefg.F
Either I am not be able to compile successfully, or even when able to compile, I cannot run the generated mex file. I get the following error:
??? Error using ==> yprimef
YPRIME requires two input arguments

Please change the datatype of PLHS(*) and PRHS(*) to MWSIZE such that automatically the correct datatype for your compiler is used.
