Open Live Script

Create and triangulate a polygon.

t = 0.05:0.5:2*pi;
x1 = cos(t);
y1 = sin(t);
x2 = 0.5*cos(t);
y2 = 0.5*sin(t);
polyin = polyshape({x1,x2},{y1,y2})
polyin = 
  polyshape with properties:

      Vertices: [27×2 double]
    NumRegions: 1
      NumHoles: 1


plot(polyin)

Figure contains an axes object. The axes object contains an object of type polygon.

T = triangulation(polyin)
T = 
  triangulation with properties:

              Points: [26×2 double]
    ConnectivityList: [26×3 double]


triplot(T)

Figure contains an axes object. The axes object contains an object of type line.
