matlab cylinder

Matlab基本函数-cylinder函数

1、cylinder函数：绘制三维圆柱图

2、用法说明：

(1)[x,y,z]=cylinder 函数返回一半径和高度都为1的圆柱体x，y，z轴的坐标值，圆柱体沿其周长有20个等距分布的点

(2)[x,y,z]=cylinder(r) 函数一个半径为r、高度为1的圆柱体的x，y，z轴的坐标值，圆柱体沿其周长有20个等距分布的点

(3)[x,y,z]=cylinder(r,n) 函数一个半径为r、高度为1的圆柱体的x，y，z轴的坐标值，圆柱体沿其周长有n个等距分布的点

(4)cylinder(...) 函数只绘制圆柱，没有任何的输出参量。其他参量及结果同上

3、实例
