quiver: Add scale factor and input validation BISTs (bug #39552)
* scripts/plot/draw/quiver.m: Add BISTs for too few inputs. Add BISTs to
verify single and multiple arrow quiver plots honor scaling factor.

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]);
