Public Functions

virtual int solve_rc(const double a3, const double b3, const double c3, const double d3, double &x1, std::complex<double> &x2, std::complex<double> &x3)

Solves the polynomial \( a_3 x^3 + b_3 x^2 + c_3 x + d_3= 0 \) giving the real solution \( x=x_1 \) and two complex solutions \( x=x_2 \) and \( x=x_3 \) .
