Guillermo,
list1 = {a, b, c, d, e};
ListConvolve[{1, 1}/2, list1]//Simplify
{(a + b)/2, (b + c)/2, (c + d)/2, (d + e)/2}

I have a list:
list1 = {a, b, c, d, e};
I want manipulate the list to obtain:
(*Out[]:{(a + b)/2, (b + c)/2, (c + d)/2, (d + e)/2}*)
It can be done for this function
f[data_List] := Drop[Plus @@ NestList[RotateRight, data,
1], 1]/2
f[list1]
but I am sure that some member of the group can find a more elegant
function. I
will appreciate to know it.
Thanks
Guillermo Sanchez
