interpolate

public static double[] interpolate(double[] x,
 double[] y,
 double[] xi,
 Interpolator.InterpolationAlgorithm method,
 boolean extrapolate)

Interpolates input data and evaluates the interpolation at a set of desired points.

Parameters:

x - input x data.

y - input y data.

xi - x points to evaluate the interpolation at.

method - interpolation method to use.

extrapolate - true if extrapolation is to be used for values outside of the x range; false if values outside the x range should return NaN.

Returns:

y values interpolated at points xi if xi is in range(x), and y values extrapolated based on the extrapolate flag if xi is not in range(x).
