Hello, yes please feel free to send a patch. Is the new algorithm better than the existing one? Can you demonstrate why its better?

Hi

Is GSL still working on new features?

I am looking at gsl_poly_complex_solve which computes the roots of polynomials.
There are other ways (better?) of computing roots of polynomials. I am looking 
at NAG's c02aac which uses a technique detailed in Cameron 2008.
Source code (fortran/MIT license) is here: 
https://github.com/trcameron/FPML/blob/master/src/fpml.f90

I am thinking of re-implementing this function in C and adding it to GSL.
We can legally change license to GPL.

Would you accept it?

Regards
Hugo
