Hi everyone,
Suppose I have a matrix:
a = [4 2 1;1 9 6;4 22 4;12 15 1;1 6 8;5 2 6];
I want to summing every two rows together and write in matrix b:
Such as:
b= [23; 58; 28]
details of calculation:
23 = a (1,:) + a (2,:)
58 = a (3,:) + a (4,:)
28 = a (5,:) + a (6,:)
Can anyone help me please?

a = [4 2 1;1 9 6;4 22 4;12 15 1;1 6 8;5 2 6]
b=sum(reshape(a',2*size(a,2),[]))
