Member Function Documentation

virtual int gsl_poly_real_coeff::solve_rc ( int  n,
const double  co[],
std::complex< double >  ro[] 
) [virtual]
Note:
In order to be consistent with the other solve_rc() functions, the ordering of the coefficients is reversed with respect to gsl_poly_complex_solve(). The leading coefficient is stored in co[0] and the constant term is stored in co[n].

Implements poly_real_coeff.
