Class MandelbrotMap

java.lang.Object
  JSci.maths.chaos.MandelbrotMap

All Implemented Interfaces:

ComplexMapping

public final class MandelbrotMap
extends java.lang.Object
implements ComplexMapping

The MandelbrotMap class provides an object that encapsulates the Mandelbrot map. z_n+1 = z_n² + c.

Field Summary

static double

CONVERGENT_BOUND A complex number z such that |z| > CONVERGENT_BOUND will diverge under this map.

Constructor Summary

MandelbrotMap(Complex aval)
Constructs a Mandelbrot map.

MandelbrotMap(double aval)
Constructs a Mandelbrot map.

Method Summary

Complex	getConstant() Returns the constant.
Complex	iterate(int n, Complex z) Iterates the map.
double	iterate(int n, double x) Iterates the map.
Complex	map(Complex z) Performs the mapping.
double	map(double x) Performs the mapping.
Complex	map(double real, double imag) Performs the mapping.
