Computes an interpolating function for the data set.

Specified by:

interpolate in interface TrivariateRealGridInterpolator

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:

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