Method Details

interpolate

public TricubicInterpolatingFunction interpolate(double[] xval,
 double[] yval,
 double[] zval,
 double[][][] fval)
                                          throws MathIllegalArgumentException

Compute an interpolating function for the dataset.

Specified by:

interpolate in interface TrivariateGridInterpolator

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.

zval - All the z-coordinates of the interpolation points, sorted in increasing order.

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

Returns:

a function that interpolates the data set.

Throws:

MathIllegalArgumentException - if any of the arrays has zero length.
