Thread Subject: how i create the mex file of this subroutine

hello everybody;

i have this fortran subroutine: http://ab-82.ifrance.com/FFLD.f

i want create the mex file but there are many "COMMON" blocs that i dont know with what i replace them

thank's

You don't have to replace them at all. Just write a mexFunction wrapper that takes the inputs from MATLAB and then sets the appropriate arguments & common block variables, and then call the subroutine. Then copy the subroutine outputs into the mxArray variables you are returning to MATLAB.

hi James;
in this tutorial: http://hal.archives-ouvertes.fr/docs/00/06/99/95/PDF/RT-0176.pdf
they say that all COMMON blocks must be replaced

This pdf file is incorrect. You do *not* have to replace COMMON blocks. They work just fine. It may be beneficial to replace them to make the code cleaner and easier to read & maintain, but there is no technical reason why they *must* be replaced.

so i write the interface mex file and i compile it. then i use it like any library.??

No. If you write a mex interface for the routine and compile it, then it would be used just like a regular MATLAB function or m-file, not a library. If you want a dll library that you can use with loadlibrary etc., then you don't write a mex interface for it, you just compile it as a library.
