Hello,
The error on the root should be
Hi,
Great work on the GSL, I love using it in my research.
I'm using the GSL in my research to solve arbitrary polynomials of order up to
4. I've written a little wrapper around the GSL to use
gsl_poly_complex_solve_quadratic() for quadratics and
gsl_poly_complex_solve_cubic() for cubics, and
