org.apache.commons.math3.analysis.solvers.AbstractUnivariateSolver
org.apache.commons.math3.analysis.solvers.RiddersSolver
public class RiddersSolver
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.

protected double doSolve()
throws TooManyEvaluationsException,
NoBracketingException
doSolve in class BaseAbstractUnivariateSolver<UnivariateFunction>TooManyEvaluationsException - if the maximal number of evaluations
is exceeded.
NoBracketingException - if the initial search interval does not bracket
a root and the solver requires it.
