Hi
I have 2 vectors
A=[8,4,5,2,4,6,4,8];
K=[1,3,5,1]
I want to create a third vector like this:
C(1)=sum(A(1))
C(2)=sum(A(1:3))
C(3)=sum(A(1:5))
C(4)=sum(A(1))
Without using a for loop ( this is an example, the vectors I have are larger )
Thanks
Shani

There might be faster ways depending on K.
A = [8,4,5,2,4,6,4,8];
K = [1,3,5,1]
x = cumsum(A);
x(k)
