matlab凸包检测

% 创建一个3D点集

points = 1 2 3; 4 5 6; 7 8 9; 10 11 12; 13 14 15;

% 使用convhull函数计算凸包

hull = convhull(points);

% 输出凸包点的索引

disp('Convex Hull Indices:');

disp(hull);

% 绘制点集和凸包

figure;

scatter3(points(:,1), points(:,2), points(:,3), 'filled');

hold on;

scatter3(points(hull,1), points(hull,2), points(hull,3), 'r', 'filled');

title('3D Convex Hull');

grid on;

axis equal;
