By ## default the plot is over the domain @code{0 <= @var{t} <= 2*pi} ## with 500 points. ## ## If @var{dom} is a two element vector, it represents the minimum and maximum ## values of @var{t}. ## ## @var{n} is a scalar defining the number of points to use in plotting the ## function. ## ## If the @qcode{"animate"} option is given then the plotting is animated ## in the style of @code{comet3}. ## ## 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 ## @group ## fx = @@(t) cos (t); ## fy = @@(t) sin (t); ## fz = @@(t) t; ## ezplot3 (fx, fy, fz, [0, 10*pi], 100); ## @end group ## @end example ## ## @seealso{plot3, comet3, ezplot, ezmesh, ezsurf} ## @end deftypefn function h = ezplot3 (varargin) [htmp, needusage] = __ezplot__ ("plot3", varargin{:}); if (needusage) print_usage (); endif if (nargout > 0) h = htmp; endif endfunction %!demo %! clf; %! fx = @(t) cos (t); %! fy = @(t) sin (t); %! fz = @(t) t; %! ezplot3 (fx, fy, fz, [0, 10*pi]); %!demo %! clf; %! fx = @(t) cos (t); %! fy = @(t) sin (t); %! fz = @(t) t; %! ezplot3 (fx, fy, fz, [0, 5*pi], "animate");
