Summing Certain pattern of elements in vector without using for loop

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)

output = 1×2

10 26
