rmholes

删除 polyshape 中的孔

语法

polyout = rmholes(polyin)

polyout = rmholes(polyin) 返回一个 polyshape 对象，此对象由删除所有孔边界之后的多边形 polyin 的实心边界组成。

创建具有一个孔的多边形。

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.

创建一个删除孔之后的新多边形。

polyout = rmholes(polyin)

polyout = 
  polyshape with properties:

      Vertices: [13×2 double]
    NumRegions: 1
      NumHoles: 0

plot(polyout)

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

输入 polyshape，指定为标量、向量、矩阵或多维数组。
