N = 10;
X = ones(N); % create a matrix of 1s
X = [X(1:N-3,:) ; 8*ones(1,N) ; X(N-2:end,:)]; % add a row of 8s between (N-3)th and (N-2)th row
X = [X(:,1) 8*ones(N+1,1) X(:,2:end)]; % add a column of 8s between 1st and 2nd columns

I didn't add comments because I thought it was self-explanatory. Anyway, I have edited my answer to include comments.
