How to know which loop is being calculated?
显示 更早的评论
Hi all,
I have a k = 1:100 and j = 1:500 where the second one is loop within the first loop. How can I find out which loop is being calculated when I click run? For instance, I want to know after 20 minutes of running, is MATLAB running the first loop k=1 and j =250? or is it k=1 and j=10? I want to know which loop is being calculated.
Thanks

Hello,
To find out which step the loop is processing, you can always click pause and check "k" and "j".
However, you can also add few lines of command to automatically inform you the process.
For example,
for k = 1:100
if mod(k,10) == 0
fprintf(['Processed: k=' num2str(k) '\n']);
end
for j = 1:500
if mod(j,50) == 0
fprintf(['j=' num2str(j) ' processed \n']);
end
end
end
the above code will give you the value of "k" whenever it becomes the multiple of 10 (i.e. 10, 20, 30, and so on) and the value of "j" when it becomes the multiple of 50.
Hope this helps!
Best,
SungJun
