Open Live Script

Create a polygon with a hole.

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: [27x2 double]
    NumRegions: 1
      NumHoles: 1


plot(polyin)

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

Create a new polygon with the hole removed.

polyout = rmholes(polyin)
polyout = 
  polyshape with properties:

      Vertices: [13x2 double]
    NumRegions: 1
      NumHoles: 0


plot(polyout)

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