cylinder

PURPOSE ^

% Generates three matrices in @code{meshgrid} format, such that

SYNOPSIS ^

function [xx, yy, zz] = cylinder (varargin)

DESCRIPTION ^

% -*- texinfo -*-
% @deftypefn {Function File} {} cylinder
% @deftypefnx {Function File} {} cylinder (@var{r})
% @deftypefnx {Function File} {} cylinder (@var{r}, @var{n})
% @deftypefnx {Function File} {[@var{x}, @var{y}, @var{z}] =} cylinder (@dots{})
% @deftypefnx {Function File} {} cylinder (@var{ax}, @dots{})
% Generates three matrices in @code{meshgrid} format, such that
% @code{surf (@var{x}, @var{y}, @var{z})} generates a unit cylinder.
% The matrices are of size @code{@var{n}+1}-by-@code{@var{n}+1}. 
% @var{r} is a vector containing the radius along the z-axis.
% If @var{n} or @var{r} are omitted then default values of 20 or [1 1]
% are assumed.
%
% Called with no return arguments, @code{cylinder} calls directly
% @code{surf (@var{x}, @var{y}, @var{z})}.  If an axes handle @var{ax}
% is passed as the first argument, the surface is plotted to this set
% of axes.
%
% Examples:
% @example
% @group
% disp ('plotting a cone')
% [x, y, z] = cylinder (10:-1:0,50);
% surf (x, y, z);
% @end group
% @end example
% @seealso{sphere}
% @end deftypefn
