I have two vectors:
A= 2 8 3 6 1 9 5 4 3 7 10 %ranperm(10)
i=1:10
I would like to find for every i , the two closest neighbors of each side.
For example:
for i=1
neighbors= 2,8
for i=2
neighbors= 2,3,6
for i=3
neighbors= 2,8,6,1
for i=10
neighbors= 4,3
...

This will do it:
A= [2 8 3 6 1 9 5 4 3 7 10] %ranperm(10)
for k = 1 : length(A)
firstIndex = max(k-1, 1);
lastIndex = min(k+1, length(A));
neighbors{k} = A(firstIndex:lastIndex);
end
celldisp(neighbors) % Display in command window.

Are there specific operations you want to perform on those neighbors? The moving statistics functions on this documentation page may perform those operations directly (if you want to add them see movsum, for example) or serve as building blocks to help you perform those operations.
