如何在MATLAB中绘制不同半径的圆顶?

geometry plot matlab

[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?

我们把半径叫做x,y,z rx ry ,和 rz 分别是。

然后像这样调用函数

[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
