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.
