Alajendro - rather than creating a new waitbar on each iteration of the inner loop, just create it once and then re-use it. For example,
maxI = 2;
maxJ = 3;
cont = 1/(maxI*maxJ);
hWaitbar = waitbar(0,sprintf('Calculating i = %d, j = %d',0,0)); % create the waitbar
for i = 1:maxI
for j = 1 : maxJ
waitbar(cont, hWaitbar, sprintf('Calculating i = %d, j = %d',i,j)) % update the waitbar
cont = cont + 1/(maxI*maxJ);
pause(rand/10); % here is the code
end
end
We use the bWaitbar handle to update the waitbar with the new progress and new message.
