### interpolate

    public TricubicSplineInterpolatingFunction interpolate(double[] xval,
                                                           double[] yval,
                                                           double[] zval,
                                                           double[][][] fval)
                                                    throws MathException

  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.
