Mesh Laplacian Matlab script

Publisher review:
Mesh Laplacian - Calculate Laplacian for triangulated mesh. MESH_LAPLACIAN: Laplacian of irregular triangular meshUseage: [lap,edge] = mesh_laplacian(vertex,face)Returns 'lap', the Laplacian (2nd spatial derivative) of an irregular triangular mesh, and 'edge', the linear distances between vertices of 'face'. 'lap' and 'edge' are square, [Nvertices,Nvertices] in size, sparse in nature.It is assumed that 'vertex' contains the (x,y,z) Cartesian coordinates of each vertex and that 'face' contains the triangulation of vertex with indices into 'vertex' that are numbered from 1:Nvertices. For information about triangulation, see 'help convhull' or 'help convhulln'.The neighbouring vertices of vertex 'i' is given by:k = find(edge(i,:)); Requirements: · MATLAB Release: R12
Operating system:
Windows / Linux / Mac OS / BSD / Solaris
