Generate three matrices in meshgrid
format, such that
surf (x, y, z)
generates a unit cylinder.
The matrices are of size n+1
-by-n+1
.
r is a vector containing the radius along the z-axis.
If n or r are omitted then default values of 20 or [1 1]
are assumed.
Called with no return arguments, cylinder
calls directly
surf (x, y, z)
. If an axes handle ax
is passed as the first argument, the surface is plotted to this set
of axes.
Examples:
[x, y, z] = cylinder (10:-1:0, 50); surf (x, y, z); title ("a cone");

Generate three matrices in meshgrid
format, such that
surf (x, y, z)
generates a unit sphere.
The matrices of n+1
-by-n+1
. If n is
omitted then a default value of 20 is assumed.
Called with no return arguments, sphere
call directly
surf (x, y, z)
. If an axes handle is passed
as the first argument, the surface is plotted to this set of axes.
See also: peaks.
Generate three matrices in meshgrid
format that define an
ellipsoid. Called with no return arguments, ellipsoid
calls
directly surf (x, y, z)
. If an axes handle
is passed as the first argument, the surface is plotted to this
set of axes.
