All Implemented Interfaces:

BaseUnivariateSolver<UnivariateFunction>, UnivariateSolver, Serializable

public class RiddersSolver
extends AbstractUnivariateSolver

Implements the Ridders' Method for root finding of real univariate functions. For reference, see C. Ridders, A new algorithm for computing a single root of a real continuous function , IEEE Transactions on Circuits and Systems, 26 (1979), 979 - 980.

The function should be continuous but not necessarily smooth.
