How can I generate symmetric array?

I have an array. and i want to write it symmetry

A(:,:,k) = [ 1 2 3 4 5 6 7 8 9 10];

I want to write it as

A(:,:,k) = [ 1 2 3 4 5 6 7 8 9 10 10 9 8 7 6 5 4 3 2 1];

for k=1:N

value of A should change according perms or permutation. because perms is limited to 10.

please help.

Write the asymmetric matrix first, just the first half. Then

A = cat(3,A, A(:,:,end:-1:1));

This will put a reversed copy of A after A
