Syntax
[X,Y,Z] = cylinder
[X,Y,Z] = cylinder(r)
[X,Y,Z] = cylinder(r,n)
cylinder(axes_handle,...)
cylinder(...)
Description
cylinder generates x-, y-,
and z-coordinates of a unit cylinder. You can
draw the cylindrical object using surf or mesh,
or draw it immediately by not providing output arguments.
[X,Y,Z] = cylinder returns
the x-, y-, and z-coordinates
of a cylinder with a radius equal to 1. The cylinder
has 20 equally spaced points around its circumference.
[X,Y,Z] = cylinder(r) returns
the x-, y-, and z-coordinates
of a cylinder using r to define a profile curve. cylinder treats
each element in r as a radius at equally spaced
heights along the unit height of the cylinder. The cylinder has 20
equally spaced points around its circumference.
[X,Y,Z] = cylinder(r,n) returns
the x-, y-, and z-coordinates
of a cylinder based on the profile curve defined by vector r.
The cylinder has n equally spaced points around
its circumference.
cylinder(axes_handle,...) plots
into the axes with handle axes_handle instead of
the current axes (gca).
cylinder(...), with no output
arguments, plots the cylinder using surf.
