SYNOPSIS

DESCRIPTION

% -*- texinfo -*-
% @deftypefn {Function File} {} gca 
% Return a handle to the current axis object.  If no axis object
% exists, create one and return its handle.  The handle may then be
% used to examine or set properties of the axes.  For example,
%
% @example
% @group
% ax = gca ;
% set (ax, 'position', [0.5, 0.5, 0.5, 0.5]);
% @end group
% @end example
%
% @noindent
% creates an empty axes object, then changes its location and size in
% the figure window.
% @seealso{get, set}
% @end deftypefn
