Progress/percent complete bar

So my question/problem is that I am trying to make a window appear that states the estimated completion time of my code, the total time the code has been running, and the percent complete the code is. I tried to use the waitbar and progress bar functions but they both run using a for loop with many iterations. I can't use these functions because my code takes approximately 3 hours to run and to run a certain amount iterations of a 3 hour code would take days. So does anyone have any advice on how to have some sort of window appear that updates the specified wants seen above as my code proceeds to run?

I do not understand the question. What is the problem with waitbar? What does "They run using a for loop with many iterations" mean? I do not see, why you cannot use waitbar, when your code needs 3 hours. What is the actual problem? That waitbar is too small to show the progress?

I know this isn't what you wanted, but I occasionally add a breakpoint to pause the program, look at the iteration variable (ex for i = 1:n, i would peek at i's value in the variables section), do some mental math comparing i to n, remove the breakpoint, and press continue. In python there are some good answers, but with my code in matlab, I don't trust myself to interact with I/O without tanking the efficency, so this is my bandaid solution.

Take a look at the waitbar(). It displays a figure that shows what percentage of a calculation is complete. Also take a look at Code Performance in the documentation. Moreover take a look at these two. ( 1 and 2 )

There is quite a bit of overhead in updating the waitbar, so it's good to use mod to alter the update rate, e.g. if Nt is the total number of i you expect to run in your loop...
hw = waitbar(0,'Running...');
for i = 1:Nt
%% code here that does things...
if mod(i,floor(Nt/10))<1e-2
waitbar(i/Nt,hw);
end
end

Hello,
Let say you have a loop that runs for 3 hours
for i = 1: 3 hours
i
end
if i is the first hour window then you can have at the end of your code something like this
for i = 1: 3
if i==1
display('33.3percentage completed')
elseif i==2
display('66.7percentage completed')
else
display('100percentage completed')
end
end
