suppose I have a loop

for i=1:10
    T(i,:)='NY';
end

then I want to clear the index variable 'i'. One way is to do

clear i

But is there a simpler way?

I agree that it will not matter from the execution perspective. But I need to send a script to a person and that person is not a programmer. So I need to clean up eveything as much as I can.

It would be very useful if there was an option to have Matlab always clear the loop variable on exit from the loop. That is to say, the loop variable should have a scope only within the loop.

As things stand, the careful programmer has to put "clear loopvariable" after every closing "end" statement, which is tedious.
