The module uses central differencing for uniform and perimeter lattices, and NAG routines for curvilinear lattices. The NAG routines employ a quadratic Shepard method that handles duplicate points and coplanar points.
This module is meant as a replacement for Gradient and Gradient3D.
Port: Lattice In
The input lattice.
A scale factor to be applied to the output vector.
If the input data is a vector, this selects the data channel.
The output lattice of vectors.
