Progress Bar and for loop

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)

It says the waitbar has too many input arguments. I am using 2018b if that has anything to do with it.

Can you show the code which causes the error. R2018b allow the input arguments used in my code.

Here is the code that causes the error

Error using waitbar
Too many input arguments.

Error in Driver_Pattern_Feedback_r13 (line 76)
f = waitbar(0, 'Starting');

.

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

I am using MATLAB 2018b. Ameer's code works as expected.

I suspect Noah's code includes something else that interferred with this minimum working example.

progressbar seems to be a function from MATLAB File Exchange, while waitbar is built in MATLAB.
