MATLAB的小小小命令

h = waitbar(x,‘message‘)
waitbar(x,‘message‘,‘CreateCancelBtn‘,‘button_callback‘)
waitbar(x,‘message‘,property_name,property_value,...)
waitbar(x)
waitbar(x,h)
waitbar(x,h,‘updated message‘)

example：
h = waitbar(0,‘Please wait...‘);
steps = 1000;
for step = 1:steps
    % computations take place here
    waitbar(step / steps)
end
close(h)
