Class Newton

java.lang.Object
  physics.Newton

public class Newton
extends java.lang.Object

This class contains the logic required to perform netwon's method of iterative root finding on single variable functions.

Nested Class Summary

static interface	Newton.Function Newton.Function is an interface which specifies a function whose roots can be found by this class.
static class	Newton.Result Newton.Result is a record type which aggregates the results of evaluating both a function at a point and its derriviative.

Field Summary

static Newton.Result

UNDEFINED Conveience name for an undefined function result

Method Summary

static double	findRoot(Newton.Function function, double initial_t) Performs netwon's method on function starting at initial_t and returns the solution.
