collapse all in page

Syntax

sz = size(TR)

Description

example

sz = size(TR) returns the size of the triangulation connectivity list in the property TR.ConnectivityList. The output sz is a two-element row vector. The first element is the number of triangles or tetrahedra in the triangulation, and the second element is the number of vertices per triangle (three) or tetrahedron (four).

Create a 2-D triangulation. 

P = [ 2.5    8.0
      6.5    8.0
      2.5    5.0
      6.5    5.0
      1.0    6.5
      8.0    6.5];

C = [5  3  1;
     3  2  1;
     3  4  2;
     4  6  2];

TR = triangulation(C,P)
TR = 
  triangulation with properties:

              Points: [6x2 double]
    ConnectivityList: [4x3 double]

Get the size of the connectivity list. The triangulation has 4 triangles, and each triangle has 3 vertices.
