Matlab, automatically delete the index variable after the execution of a loop, Part 2

https://stackoverflow.com/questions/9850628/matlab-automatically-delete-the-index-variable-after-the-execution-of-a-loop

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?

How is this part 2, since you asked identically the same question on stackoverflow? Is this just a general survey of every possible site, in case you can get a different answer? You cannot automatically delete a loop index variable after a loop. This is part of the language, and expected.

The simple answer is to just learn to use functions, then all of your spurious variables go away.

I'd not even bother. In these days of computers with 32 billion bytes of RAM, why bother clearing 8 bytes?

Anyway how much simpler to you want? It's only 6 characters on one line of code. It won't get any simpler.

[John D'Errico]

I agree. Clearing the variable is just a waste of CPU cycles, however you might do it. Why bother?

[Steven Lord]

then I want to clear the index variable 'i'

Why? What benefit do you hope to gain from doing this?

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.

That is the simpler way.

If you have multiple loops , use the same index variable for all of them and finally use

clear index_variable

Can have some options I guess
