%
% Usage
%
% Toggles the hold state on the currently active plot. The
% general syntax for its use is
%
% hold(state)
%
% where state is either
%
% hold('on')
%
% to turn hold on, or
%
% hold('off')
%
% to turn hold off. If you specify no argument then
% hold toggles the state of the hold:
%
% hold
%
% You can also specify a particular axis to the hold command
%
% hold(handle,...)
%
% where handle is the handle for a particular axis.
