孔边界转换为 polyshape
对象数组
说明
示例
孔边界数组
创建包含两个实心区域和两个孔的多边形。将孔边界转换为 polyshape
对象数组。
P = [0 0; 0 2; 2 2; 2 0; NaN NaN; 0.5 0.5; 0.5 1.5; 1.5 1.5; 1.5 0.5; ...
NaN NaN; 3 0.5; 3.5 1.5; 4 0.5; NaN NaN; 3.25 0.6; 3.75 0.6; 3.5 1];
polyin = polyshape(P);
plot(polyin)
xlim([-0.5 4.5])
ylim([-0.5 2.5])
polyout = holes(polyin)
polyout = 2x1 polyshape array with properties: Vertices NumRegions NumHoles
plot(polyout) xlim([-0.5 4.5]) ylim([-0.5 2.5])
