Oh! I see the question was edited. s starts as an image, then becomes an iterator. That's confusing! There are 26 letters in the alphabet, you don't have to limit yourself to just 2. Even better, use words for variable names as this makes the intent of the code clearer.
What is the desired output? What size should za be?

Sounds like homework to me.
Do you have to use a loop? The normal matlab way is simply:
za = (1:50).^2;
If you do have to use a loop, index your za.
Note that there is a big difference between 2.^x and x.^2. The power operation is not commutative.

In your question, you wrote "calculate square" which .^2.
What does (image) mean? Perhaps, you should show a numerical example of input and corresponding desired output.
