I'm sorry for the stupid question, but If i have an array A = [1,2,5,7,9] and i want an array B = [1,3,8,15,24], progressive sum of the elemts in A, what is the code that returns me B? Thanks!

B = cumsum(A);
You could have learned about this function by reading the help for sum. At the bottom of the help, you would see a see also line. That reads:
See also prod, cumsum, diff, accumarray, isfloat.
