Interface Solver

All Known Implementing Classes:

Cubic, JenkinsTraubReal, Linear, Polyroot, Quadratic, Quartic

public interface Solver

All analytical root finding formulae for polynomials implement this interface.

This interface facilitates the implementation of strategy pattern, hence switching implementations dynamically.

Nested Class Summary

static class	Solver.RootFindingException RuntimeException thrown when it fails to find a root for a polynomial.
static class	Solver.Type the type of polynomials the solver can solve

Method Summary

NumberList	solve(Polynomial polynomial) Compute the roots for a polynomial.
Solver.Type	type() Get the type of the solver.
