function [summa,index=nba_aj(b,n)
s=length(b);
i=0;
if n>s
a=0
k=-1
elseif n<=s
q=movsum(b,n)
summa=max(q)
what should i do after this for index finding
% here i want to know the index
can you guys help me the required answer is
summa=13,index=4 b=[1 2 3 4 5 4 3 2 1] n=3
summa=5,index-5 b=[1 2 3 4 5 4 3 2 1] n=1

As Walter has said already: This topic has been discussed already and you find a working solution there also. All you need is reading the documentation of movsum:
doc movsum
and to learn, why you have to ignore the marginal elements by setting 'EndPoints' to 'discard'. In addition you have to use the 2nd output of max.
Pleae note that posting working solution of homework questions is not really useful.
