interpolate

public BicubicSplineInterpolatingFunction interpolate(double[] xval,
                                                      double[] yval,
                                                      double[][] fval)

Compute an interpolating function for the dataset.

Specified by:

interpolate in interface BivariateGridInterpolator

Parameters:

xval - All the x-coordinates of the interpolation points, sorted in increasing order.

yval - All the y-coordinates of the interpolation points, sorted in increasing order.

fval - The values of the interpolation points on all the grid knots: fval[i][j] = f(xval[i], yval[j]) .

Returns:

a function which interpolates the dataset.
