Another possibility is to _interface_ Fortran with C. It requires some
rudumentary knowledge of _both_ languages, but usually pays the effort.
(I'm an experienced Fortran programmer but I learned a few bits of C.)

For example NAG brings out the so called "C header files".
If you include these in a C-program, then you can invoke routines from
the NAG Fortran library (object codes), as if they were written in C.

Why should you re-invent the wheel, huh?

It's all in Fortran, of course.
