GUI Examples #9:Explore user notification
function [] = GUI_9() % Demonstrate one way to let the user know a process is running. % Creates a pushbutton which, when pushed, simulates some process running % in the background and lets the user know this is happening by a text and % color change. When the process is finished, the button returns to % normal. CAREFULLY READ THE COMMENTS BELOW IF YOU PLAN ON USING THIS % METHOD IN ONE OF YOUR GUIs. % % % Author: Matt Fig % Date: 7/15/2009 S.fh = figure('units','pixels',... 'position',[300 300 200 100],...

Here just sort a vector. A = rand(3000000,1); A = sort(A); set(h,'str','Push Me','backg',col) % Now reset the button features.
