Function find_face_edges 

Source 
pub fn find_face_edges(
    x: &[Float],
    y: &[Float],
    z: &[Float],
    pmax: usize,
    qmax: usize,
) -> Vec<FaceDiff>
Expand description

Compute forward and backward differences along each direction for a 2D face.

x, y, z are flat arrays of length pmax * qmax, stored row-major (p varies fastest within each row of q).
