如何在MATLAB中绘制具有/不同半径的圆顶？

Question

我需要绘制具有不同半径的圆顶（或半球）。我被告知如何在上一个问题上绘制shpere：

[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 

Does anyone know how to plot a dome (aka half sphere) in MATLAB...or anyother programming language?

但我需要x，y和z组件的高度都不同。

如何更改代码？

Answer 1

我们分别在x，y和z rx，ry和rz中调用半径。

然后你调用这个函数

[x,y,z] = sphere;      %# Makes a 21-by-21 point unit 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 
rx = 3;ry = 4;rz = 9;  %# Define rx, ry, rz
surf(rx*x,ry*y,rz*z);  %# Plot the surface, multiplying unit coordinates with radii 
axis equal;            %# Make the scaling on the x, y, and z axes equal
