I find those instructions hard to understand, particularly to someone without experience with C.

I have once posted one example here: [Calling a Fortran routine from a library which uses LAPACK - #5 by lmiq](https://discourse.julialang.org/t/calling-a-fortran-routine-from-a-library-which-uses-lapack/49124/5) (but I arrived to succeed in those by finding several examples around, not reading the docs).

To do the same with that code, you need first to convert the program into a subroutine, but the way that is structured doesn’t help.

Probably the first thing to ask is how fast you need that to be. Maybe parsing the output is good enough.
