% Plot a scatter plot of the data.  A marker is plotted at each point 
% defined by the points in the vectors @var{x} and @var{y}.  The size of
% the markers used is determined by the @var{s}, which can be a scalar, 
% a vector of the same length of @var{x} and @var{y}.  If @var{s} is not 
% given or is an empty matrix, then the default value of 8 points is used.
% The color of the markers is determined by @var{c}, which can be a string
% defining a fixed color, a 3 element vector giving the red, green and blue 
% components of the color, a vector of the same length as @var{x} that gives
% a scaled index into the current colormap, or a @var{n}-by-3 matrix defining
% the colors of each of the markers individually.
% The marker to use can be changed with the @var{style} argument, that is a 
% string defining a marker in the same manner as the @code{plot} command. 
% If the argument 'filled' is given then the markers as filled.  All 
% additional arguments are passed to the underlying patch command.
% The optional return value @var{h} provides a handle to the patch object
% @example
% @group
% x = randn (100, 1);
% y = randn (100, 1);
% scatter (x, y, [], sqrt(x.^2 + y.^2));
% @end group
% @end example
% @seealso{plot, patch, scatter3}
% @end deftypefn
