Taking a wild guess:
for k1 = 1:20
if (k1 == 1) | (k1 == 20)
continue
end
% Do Something
end
If k1 is 1 or 20, the loop continues to the next iteration without doing anything after the if block. Otherwise, it continues to do whatever is in the loop.

This, of course, could be simply written as
for k2 = 2:19
%do something
end
So, I'm not sure why the OP is asking the question.

My guess is that at 1 and 20 it does only one set of operations, and in between, other operations as well. We don’t know the details.

Is this what you are looking for?
for j = 1:20
if j==1 || j==20, continue; end
your_code_goes_here
end
This executes everything after the if except when j is 1 or 20.

You mean something like this because your question is not clear
while stoploop=0
stoploop=j==1|j==20
end
A test you can see it is only true on 1 and 20
for j=1:20
stoploop(j)=j==1|j==20
end
