how to Sum Array with "for" loop ?

need help, how i can get value of c(t)=b(1)+b(2)+...+b(t) in matlab ? e.g. a=0 for t=1:5 b=a+t end

will result b = [1] b = [1 2] b = [1 2 3] b = [1 2 3 4] b = [1 2 3 4 5]

then i want to make

c(1)=b(1) c(2)=b(1)+b(2) ... c(t)=b(1)+b(2)+...+b(t)

The question is not clear. "b=[1], b=[1,2]" is not a result, but multiple results assigned to the same variable.

Currently the best answer would be:

c = cumsum(1:5);

But is this really what you are looking for?

Use cumsum, e.g.:

>> B = 1:5;
>> cumsum(B)
ans =
    1    3    6   10   15
