matlab中凸包和凸缺陷的代码

在MATLAB中，可以使用`convhull`函数计算凸包，使用`convexHull`函数计算凸缺陷。下面是几个示例代码:

1. 计算凸包:

% 创建一个随机的点集
points = rand(10, 2);

% 计算凸包
k = convhull(points(:,1), points(:,2));

% 绘制凸包
plot(points(:,1), points(:,2), 'o');
hold on;
plot(points(k,1), points(k,2), 'r');
hold off;

2. 计算凸缺陷:

% 创建一个随机的点集
points = rand(10, 2);

% 计算凸包
k = convhull(points(:,), points(:,2));

% 计算凸缺陷
defects = convexHull(points(:,1), points(:,2));

% 绘制凸包和凸缺陷
plot(points(:,1), points(:,2), 'o');
hold on;
plot(points(k,1), points(k,2), 'r');
plot(points(defects,1), points(defects,2), 'g');
hold off;
