有谁知道如何在MATLAB ...或任何其他编程语言中绘制圆顶(也称为半球形)?
问题描述：
我需要绘制一个圆顶或半球形，并且能够更改圆顶的尺寸.我认为MATLAB是我的最佳选择.
I need to plot a dome or half a sphere and be able to change the dimensions of the dome. I figured MATLAB would be my best choice.
有什么建议吗?
谢谢

The SPHERE function generates x, y, and z coordinates for a spherical surface. You just have to remove points corresponding to the bottom of the sphere to make a dome. For example:
[x,y,z] = sphere; %# Makes a 21-by-21 point sphere
x = x(11:end,:); %# Keep top 11 x points
y = y(11:end,:); %# Keep top 11 y points
z = z(11:end,:); %# Keep top 11 z points
r = 3; %# A radius value
surf(r.*x,r.*y,r.*z); %# Plot the surface
axis equal; %# Make the scaling on the x, y, and z axes equal
