I would like to write a computation that will take a vector of 1xN length and then add adjacent matrix values .

I would like to write a computation that will take a vector of 1xN length and then add adjacent matrix values .

e.g. [a+b,c+d,e+f,g+h,....etc]

My thoughts were to write something along the lines of n-(n-1), n-(n-2) to calculate this step.

However I don't want to continuously write this for a N=256 row.

How could I do this?

input (a,b,c,d,e,f,g,h.....etc.)

output (a+b,c+d,e+f,g+h,....etc.)

Where V is your vector (containing an even number of elements):

V(1:2:end)+V(2:2:end)
