Perhaps something like this

N = 6; % Size of matrix
a = 1; % Example value
b = 2; % Example value

A = a*eye(N) + b*fliplr(eye(N));

A =
     1     0     0     0     0     2
     0     1     0     0     2     0
     0     0     1     2     0     0
     0     0     2     1     0     0
     0     2     0     0     1     0
     2     0     0     0     0     1
