##
## Plot a 2-D function in polar coordinates.
##
## The function @var{f} is a string, inline function, or function handle with
## a single argument. The expected form of the function is
## @code{@var{rho} = @var{f}(@var{theta})}.
## By default the plot is over the domain @code{0 <= @var{theta} <= 2*pi}
## with 500 points.
##
## If @var{dom} is a two element vector, it represents the minimum and maximum
## values of @var{theta}.
##
## @var{n} is a scalar defining the number of points to use in plotting
## the function.
##
## If the first argument @var{hax} is an axes handle, then plot into this axes,
## rather than the current axes returned by @code{gca}.
##
## The optional return value @var{h} is a graphics handle to the created plot.
##
## Example:
##
## @example
## ezpolar (@@(t) sin (5/4 * t), [0, 8*pi]);
## @end example
##
## @seealso{polar, ezplot}
## @end deftypefn
function h = ezpolar (varargin)
[htmp, needusage] = __ezplot__ ("polar", varargin{:});
if (needusage)
print_usage ();
endif
if (nargout > 0)
h = htmp;
endif
endfunction
%!demo
%! clf;
%! ezpolar (@(t) sin (5/4 * t), [0, 8*pi]);
