interpolate

public NearestNeighbourFunction interpolate(double[] _x,
 double[] _y)
                                     throws org.apache.commons.math3.exception.MathIllegalArgumentException,
org.apache.commons.math3.exception.DimensionMismatchException

Create a nearest neighbour function by defining covering intervals between sample points. As the order is kept, binary search for the interval bounds provides the corresponding interpolated value.

Specified by:

interpolate in interface org.apache.commons.math3.analysis.interpolation.UnivariateInterpolator

Parameters:

_x - array of sample locations of the sample points

_y - array of sample values of the corresponding sample points

Returns:

a nearest neighbour function

Throws:

org.apache.commons.math3.exception.MathIllegalArgumentException

org.apache.commons.math3.exception.DimensionMismatchException
