PATCHSLIM removes duplicate vertices in surface meshes. This function finds and removes duplicate vertices. USAGE: [v, f]=patchslim(v, f) Where v is the vertex list and f is the face list specifying vertex connectivity. v contains the vertices for all triangles [3*n x 3]. f contains the vertex lists defining each triangle face [n x 3]. This will reduce the size of typical v matrix by about a factor of 6.
