Dear Mike,

E.g.:
H = uicontrol('Style', 'listbox', ...
'Units', 'normalized', ...
'Position', [0, 0, 1, 1], ...
'String', {'First line'});
drawnow;
pause(1.0);

set(H, 'String', cat(1, get(H, 'String'), {'Second line'}));
drawnow;
pause(1.0);

set(H, 'String', cat(1, get(H, 'String'), {'Third line'}));
drawnow;
pause(1.0);

The DRAWNOW are important, if the PAUSE vanishes in a real program.
Of course you could collect the cell string anywhere else, e.g. as persistent variable, as UserData of the FIGURE, with SETAPPDATA. With the above method your program needs to remember only the handle of the listbox.

Nevertheless, I'd still prefer the standard command window.

I don't know what you mean by "format". Here's an example:


function mygui
f=figure('units','pixels','position',[30 100 500 300]);
l=uicontrol('parent',f,'style','list','units','pixels','position',[30 10 300 250],'String',{'Starting'});
pb=uicontrol('parent',f,'style','push','units','pixels','position',[30 270 80 20],'string','Run','callback',{@pb_call});


function pb_call(varargin)
cur_log = get(l,'String');
new_log = [cur_log ; {'Running ...'}];
set(l,'String',new_log);
pause(1);
new_log = [cur_log ; {'Running ... Done'}];
set(l,'String',new_log);
end

end

You can actually do a lot by customizing a multi-line editbox, as shown here: http://undocumentedmatlab.com/blog/rich-matlab-editbox-contents/ (scroll down until you see the log example and screenshot). All it takes is a little bit of Java magic powder...

For the record, you can also achieve similar results with a listbox
