      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.
