interpolate

MultivariateFunction interpolate(double[][] xval,
                                 double[] yval)
                                 throws MathIllegalArgumentException,
                                        DimensionMismatchException,
                                        NoDataException,
                                        NullArgumentException

Computes an interpolating function for the data set.

Parameters:

xval - the arguments for the interpolation points. xval[i][0] is the first component of interpolation point i, xval[i][1] is the second component, and so on until xval[i][d-1], the last component of that interpolation point (where d is thus the dimension of the space).

yval - the values for the interpolation points

Returns:

a function which interpolates the data set

Throws:

MathIllegalArgumentException - if the arguments violate assumptions made by the interpolation algorithm.

DimensionMismatchException - when the array dimensions are not consistent.

NoDataException - if an array has zero-length.

NullArgumentException - if the arguments are null.
