        TrivariateRealFunction interpolate​(double[] xval,
                                           double[] yval,
                                           double[] zval,
                                           double[][][] fval)
                                    throws MathException
        Computes an interpolating function for the data set.
        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:
        NoDataException - if any of the arrays has zero length.
        DimensionMismatchException - if the array lengths are inconsistent.
        MathException - if arguments violate assumptions made by the interpolation algorithm.
