sphere
Generate sphere
Syntax
sphere
sphere(n)
sphere(ax,...)
[X,Y,Z] = sphere(...)
Description
The sphere function generates the x-, y-,
and z-coordinates of a unit
sphere for use with surf and mesh.
sphere generates a sphere
consisting of 20-by-20 faces.
sphere(n) draws a surf plot
of an n-by-n sphere in the current
figure.
sphere(ax,...) creates the sphere in the
axes specified by ax instead of in the current
axes. Specify ax as the first input argument.
[X,Y,Z] = sphere(...)
returns the coordinates of the n-by-n sphere
in three matrices that are (n+1)-by-(n+1) in
size. You draw the sphere with surf(X,Y,Z) or mesh(X,Y,Z).
Examples
Plot Sphere
Generate and plot a sphere.
figure sphere
Plot Multiple Spheres
Define x, y, and z as coordinates of a sphere.
[x,y,z] = sphere;
Plot a sphere centered at the origin. Plot two more spheres centered at (3,-2,0) and (0,1,-3).
figure surf(x,y,z) hold on surf(x+3,y-2,z) % centered at (3,-2,0) surf(x,y+1,z-3) % centered at (0,1,-3)
