Hi, I have a vector A (m*p)x1 and I want to create a vector B px1 where B(i)=sum_{n=0}^{m-1}A(i+p*n), e.g.
m=3;p=4;A=[12;11;10;9;8;7;6;5;4;3;2;1];B=[A(1)+A(5)+A(9);A(2)+A(6)+A(10);A(3)+A(7)+A(11);A(4)+A(8)+A(12)];
I can't use loops.

m=3;p=4;A=[12;11;10;9;8;7;6;5;4;3;2;1];B=[A(1)+A(5)+A(9);A(2)+A(6)+A(10);A(3)+A(7)+A(11);A(4)+A(8)+A(12)];
