计算一个三维表面的高斯曲率和平均曲率Matlab程序,COMPUTE GAUSSIAN AND MEAN CURVATURES OF A SURFACE

[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,

求解曲面的高斯曲率、曲率的均值及最大值、最小值。(The mean, maximum and minimum values of the curvature of the surface are obtained.)
