I have a loop. The number of iteration is very big. Usually it produce error at iteration >500. can I run the loop and stop a few step before error? If I use debug, I need to run almost 500 iteration manually and it is tiring .

what do you mean? the structure is similar to this (sorry not to post the code since it is very long):
for k= 1:10.000
%statement1 --------------
%statement2
end
and I want to stop at k=500 as example

Why don't you just run your for loop 500 times instead of 10000?

Solution 1:
dbstop if error
Then Matlab stops, when an error occurs.
Solution 2:
for k = 1:5e5
if k == 500
disp('dummy line'); % <- set a breakpoint in this line
end
... your code
end
Instead of a breakpoint, the "keyboard" command would be sufficient also.
Of course the debugger has more powerful options, but this simple methods work in other programming languages also and are easy to remember.

Use 'keyboard' command to debug.
if i = 500
keyboard
end
