Hello,
-I have this matlab code:
function [nsd]=NaivniNSD(a,b)
if a>b
a=a-b;
else
b=b-a;
end
end
nsd=a;
- when i write (a=40;b=50) i still have the answer nsd=10 in matlab. a logical analysis will be b=10 so that nsd=a=40 not 10. I don't know what is the thing that i couldn't undersntand. Thank you.

If that is indeed the function you are using, I'm surprised you don't get an error. Your
nsd = a;
is outside the function body. Put it before the last end.

I don't really understand your comment. As I said, in the code you've posted the nsd=a; is outside the body of the function. The 2nd end ends the function.
If it's not outside, then the code you've posted is not the one you're using. And the question is then, what is the actual code you're using?

The thing was in my understanding of while cycle and its behaviour to a and b,now everything is working well, even with 'end'is written like this. Thank you anyway.
