Hello,

I am needing to add a progress bar to my code that is basically one 800 line for loop. I keep looking up and trying the basic codes for progress bar already listed on mathworks but I can't seem to figure it out. Can anyone help me figure this out?

Here is the simple one I tried but it doesn't work for me by itself, and I dont know how I would implement it into the for loop either.

function basicwaitbar
f = waitbar(0,'Please wait...');
pause(.5)
waitbar(.33,f,'Loading your data');
pause(1)
waitbar(.67,f,'Processing your data');
pause(1)
waitbar(1,f,'Finishing');
pause(1)
close(f)
end

See this example

f = waitbar(0, 'Starting');
n = 100;
for i= 1:n
    % write your code here
    waitbar(i/n, f, sprintf('Progress: %d %%', floor(i/n*100)));
    pause(0.1);
end
close(f)

I found this code. Using progress bar over waitbar worked better for some reason. See below:

Demos:
    % Single bar
    m = 500;
    progressbar % Init single bar
    for i = 1:m
      pause(0.01) % Do something important
      progressbar(i/m) % Update progress bar
    end
