All Implemented Interfaces:

FunctionInt

public class Interpolate
extends MathModel
implements FunctionInt

This class provides routines for function interpolation. Include the function to be interpolated in a class that implements the interface FunctionInt or FunctionInt2 (defined below). Methods contained here are based on the Numerical Recipes (W. H. Press et al.).

 interface FunctionInt{
     double functionInt(double x);
 }

 interface FunctionInt2{
     double functionInt(double x1, double x2);
 }

Constructor Summary

Interpolate(double[] x, double[] y, int romberg, boolean rational, boolean relative)

Interpolate(int max, double xmin, double xmax, FunctionInt function2int, int romberg, boolean rational, boolean relative, boolean isLog, int rombergY, boolean rationalY, boolean relativeY, boolean logSubst)
initializes class for the 1-dimensional function

Interpolate(int max1, double x1min, double x1max, int max2, double x2min, double x2max, FunctionInt2 function2int, int romberg1, boolean rational1, boolean relative1, boolean isLog1, int romberg2, boolean rational2, boolean relative2, boolean isLog2, int rombergY, boolean rationalY, boolean relativeY, boolean logSubst)
initializes class for the 2-dimensional function

Method Summary

double	findLimit(double y) finds x: f(x)=y, 1d initialization required
double	findLimit(double x1, double y) finds x: f(a,x)=y, 2d initialization required
double	functionInt(double x) defines a function for every row
double	interpolate(double x) interpolates f(x) for 1d function
