How to write a loop for adding number

Hi,

I have 52 values a,b,c........

I need to do like below

b=a+b; c=b+c; d=c+d;............for all 52 values

How can I do this by writing a loop?

Thanks in advance

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.
