java.lang.Object
  com.softsynth.jmsl.util.LinearInterpolator

All Implemented Interfaces:

Interpolator

public class LinearInterpolator
extends java.lang.Object
implements Interpolator

Interpolate a value along a line defined by two points (x1,y1) and (x2,y2)

Author:

Constructor Summary

LinearInterpolator(double ex1, double why1, double ex2, double why2)
Construct a linear interpolator that intersects two specified points

Method Summary

double	interp(double x) Given the input x, return the y along the interpolator's linear function
static void	main(java.lang.String[] args) build an interpolator and print 20 points along the line
void	setInterp(double ex1, double why1, double ex2, double why2) Set the interpolator to calculate points along the line intersecting two specified points
java.lang.String	toString() print me
