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.

[X,Y,Z] = sphere(n) returns the coordinates of a 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).
