[John D'Errico]

Please stop using Answers as a code writing service. You have been using MATLAB for how long now? And every time you post, youe question is a confusing one like this with no attempt made by you, where you ask someone to write some code for you.

I have to agree with @John D'Errico. And, in any case, the question was too unstructured to even attempt to offer some help.

Answer 1

[Davide Masiello]

In summary:

• summation of a 1xN array A: sum(A);
• summation of all elements of a MxN array A: sum(A(:)) or sum(A,'all') (the latter works on the newer versions of MatLab only)

I would anyway suggest checking the following documentation

I am sorry, I think that's too little information, you could try to elaborate a bit more.
