[K,H,P1,P2] = surfature(X,Y,Z) returns the gaussian curvature of a surface (K), mean curvature (H), and principal curvatures (P1,P2). The inputs (X,Y,Z) are 2D arrays corresponding to the surface being analyzed.



Example

[X,Y,Z] = peaks

[K,H,P1,P2] = surfature(X,Y,Z)

surf(X,Y,Z,H, facecolor , interp )

set(gca, clim ,[-1,1])
