Method Summary

void	addData(double[] x, double[] y) Supply the interpolator with a set of data points.
double	evaluate(double x) Interpolate the estimated function to a point x to compute y^ = f(x).

Method Detail

addData

void addData(double[] x,
             double[] y)

Supply the interpolator with a set of data points. This function must be called before the interpolator can evaluate for any x.

Parameters:

x - the abscissae

y - the ordinates

evaluate

double evaluate(double x)

Interpolate the estimated function to a point x to compute y^ = f(x).

Parameters:

x - x

Returns:

f(x)
