How to update GUI with interims results of an algorithm in real time while the algorithm is still running??!

Hi mathworks community,

i have a quite simple question that i dont know how to deal with yet.

I implemented a GUI with GUIDE and run an Algorithm "heuristic.m" by pushing a PUSHBUTTON! This Algorithm produces better and better results as it converges to a better solution. I would like the user to always see the best so far solution produced by the algorithm on the GUI surface!

I tried doing so by putting the following lines in the algorithms code.

hMainGui = findobj('Tag','gui_surface')                                % find tag for GUI-Surface
handles=guidata(hMainGui)                                              % Obtain handles for GUI-components
set(handles.solution_value,'string',solution_value_best_so_far)        % Update of the GUI edit-textbox

Unfortunately i see that this code doesnt work while the algorithm is running!! But as soon as i stop the algorithm the corresponding values are written in the edit-textbox... Is there a possibility of getting a continous update during the runtime of the algorithm? What did i do wrong?

I am soo glad for your help!

Best regards, John

After you set(), call drawnow()

Thank you very much! it works perfectly now!;)
