Re: Linking my fortran subroutines with Mathematica

Hi,

just make a wrapper for your Fortran functions so you can call them from
C. Once this is done you can simply call them through the MathLink.
You could start by compiling your Fortran functions into a .so or .dll
or however the shared libraries are called on your OS. Then create a
MathLink-template and call those functions from there..

I really don't know how to explain this better since it is straight
forward and you should have a running example in a few minutes.

Cheers
Patrick
