Addition of adjacent rows of a column matrix

Hello, here is a part of my code where I am trying to add adjacent rows, i.e a(R1)+a(R2) =b(R2), a(R2)+a(R3) = b(R3) and so on. Could anyone please help me solve the issue of exceeding array bounds in position 1.

i = 2:500;

j = 2:500;

if ( i == j)

b(j,1) = a(i,1) + a(i-1,1)+ b(j-1,1);

end

Thanks in advance!

You can use movmean()

x = rand(100, 1);
y = movmean(x, 2, 'Endpoint', 'discard')
