You could certainly do this with a uicontrol object. I don't know how convenient it would be to do it this way, I guess it would depend on how large your outputs might be. Here is a function which creates such an textbox.
function [S] = txt_update
% Creates a textbox.
S.fh = figure('units','pixels',...
'position',[40 40 240 940],...
'menubar','none',...
'resize','off',...
'numbertitle','off',...
'name','Program output');
S.tx = uicontrol('style','edit',...
'units','pix',...
'position',[10 60 220 830],...
'backgroundcolor','w',...
'HorizontalAlign','left',...
'min',0,'max',10,...
'enable','inactive');
.
.
Now, do this, for example:
S = txt_update; % Create the textbox.
for ii = 1:50
A = rand(ceil(rand*2),ceil(rand*3)); % Update with numeric data.
set(S.tx,'string',cat(1,get(S.tx,'string'),{num2str(A)}))
pause(.1) % Simulate some long calculation.
end
for jj = 1:50
B = char(rand(1,9)*10+110); % Update with character data.
set(S.tx,'string',cat(1,get(S.tx,'string'),{B}))
pause(.1) % Simulate some long calculation.
end
To see the most recent data at the top, reverse the second and third arguments to the CAT function.
