Method Detail

interpolate

MultivariateRealFunction interpolate(double[][] xval,
                                     double[] yval)
                              throws MathException,
                                     java.lang.IllegalArgumentException

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:

MathException - if arguments violate assumptions made by the interpolation algorithm or some dimension mismatch occurs

java.lang.IllegalArgumentException - if there are no data (xval null or zero length)
