The simplest ## form is ## ## @example ## plot3 (@var{x}, @var{y}, @var{z}) ## @end example ## ## @noindent ## in which the arguments are taken to be the vertices of the points to ## be plotted in three dimensions. If all arguments are vectors of the ## same length, then a single continuous line is drawn. If all arguments ## are matrices, then each column of is treated as a separate line. No attempt ## is made to transpose the arguments to make the number of rows match. ## ## If only two arguments are given, as ## ## @example ## plot3 (@var{x}, @var{cplx}) ## @end example ## ## @noindent ## the real and imaginary parts of the second argument are used ## as the @var{y} and @var{z} coordinates, respectively. ## ## If only one argument is given, as ## ## @example ## plot3 (@var{cplx}) ## @end example ## ## @noindent ## the real and imaginary parts of the argument are used as the @var{y} ## and @var{z} values, and they are plotted versus their index. ## ## Arguments may also be given in groups of three as ## ## @example ## plot3 (@var{x1}, @var{y1}, @var{z1}, @var{x2}, @var{y2}, @var{z2}, @dots{}) ## @end example ## ## @noindent ## in which each set of three arguments is treated as a separate line or ## set of lines in three dimensions. ## ## To plot multiple one- or two-argument groups, separate each group ## with an empty format string, as ## ## @example ## plot3 (@var{x1}, @var{c1}, "", @var{c2}, "", @dots{}) ## @end example ## ## Multiple property-value pairs may be specified which will affect the line ## objects drawn by @code{plot3}. If the @var{fmt} argument is supplied it ## will format the line objects in the same manner as @code{plot}. ## ## If the first argument @var{hax} is an axes handle, then plot into this axis, ## 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 ## @group ## z = [0:0.05:5]; ## plot3 (cos (2*pi*z), sin (2*pi*z), z, ";helix;"); ## plot3 (z, exp (2i*pi*z), ";complex sinusoid;"); ## @end group ## @end example ## @seealso{ezplot3, plot} ## @end deftypefn ## Author: Paul Kienzle ## (modified from __plt__.m) function retval = plot3 (varargin) [hax, varargin, nargs] = __plt_get_axis_arg__ ("plot3", varargin{:}); if (nargs < 1) print_usage (); endif oldfig = []; if (!
