[Help-gsl] Doubts about GSL library

[Juan José Pena]

Dear Sir or Madame.
I am writing this email because I do work in C, and must perform
complex matrix operations. Searching the internet some library that I
could be useful, I came to you. The problem I have now is that I find
what to use to solve an equation (algebraic Riccati equation (DARE)).
Could you help in finding the function I solve the problem?
Thank you very much in advance,
Juan José Pena Martínez.
