Summing Certain pattern of elements in vector without using for loop
显示 更早的评论
I want to sum each 4 elements of a vector and make a new vector of it.
example A=[1 2 3 4 5 6 7 8]
i want B=[10 26]
for n=1:length(A)/4
B(n)=sum(A(4*n-3:4*n))
end
Can i implents this code without for loop ?

use reshape function
A=[1 2 3 4 5 6 7 8];
output=sum(reshape(A,4,[]),1)
