How to adopt a Fortran routine?

[paramaniac]

Dear Octave Community

Since there is a bug [1] in tzero.m (or in one of its subroutines from the control package) and I have absolutely no idea how to fix it, I was looking for another - working - implementation. I found a Fortran file named sszer.f in Scilab 5.2 which has no clear license information in it, but I assume it's distributed under the terms of CeCILL 2 (a French open-source license) like Scilab itself and therefore free. It's an implementation of the algorithm described in [2] and I wish to create an oct-file out of it. Unfortunately, I only have basic c++ knowledge and I don't understand Fortran code at all. Does anybody knows how to create an oct-file out of Fortran code [3] and how the function is used (especially the passed/returned arguments) ?

Thanks for any help in advance!

Regards,
Lukas

I was going to look at and try to fix tzero.m
