function fout = waitbar_j(x,whichbar, varargin)
%WAITBAR Display wait bar.
% H = WAITBAR(X,'title', property, value, property, value, ...)
% creates and displays a waitbar of fractional length X. The
% handle to the waitbar figure is returned in H.
% X should be between 0 and 1. Optional arguments property and
% value allow to set corresponding waitbar figure properties.
% Property can also be an action keyword 'CreateCancelBtn', in
% which case a cancel button will be added to the figure, and
% the passed value string will be executed upon clicking on the
% cancel button or the close figure button.
%
% WAITBAR(X) will set the length of the bar in the most recently
% created waitbar window to the fractional length X.
%
% WAITBAR(X,H) will set the length of the bar in waitbar H
% to the fractional length X.
%
% WAITBAR(X,H,'updated title') will update the title text in
% the waitbar figure, in addition to setting the fractional
% length to X.
%
% WAITBAR is typically used inside a FOR loop that performs a
% lengthy computation. A sample usage is shown below:
%
% h = waitbar(0,'Please wait...');
% for i=1:100,
% % computation here %
% waitbar(i/100,h)
% end
% close(h)
