If you think about what you're doing, it's just a cumulative sum.
Put all your variables into a vector:
vec = [a b c d .... ];
And use the cumulative sum.
out = cumsum(vec);
No loop necessary.

Creating 52 different variables is less efficient than creating a [1 x 52] vector. Then the cumsum approach will be easy.
