Constructor Detail
Instance Method Detail
Returns complex value of polinomial at complex point x
Returns array containing value at given point and all derivatives at this point.
Returns sorted array containing real roots of polinomial. Roots of higher order will be returned as separate roots
Returns array containing complex roots of polinomial.
Always returns @coeffs.size-1 number of roots.
Returns sorted array containing real roots of polinomial.
Roots that differs less then tolerance will be returned as one root
