121 by 121 Sparse Matrix

I want to create a sparse matrix (121 by 121) with A repeating in the main diagonal.

I wrote a code below to create my 11 by 11 matrix A but how do i get a 121 by 121 sparse matrix with A repeating in the main diagonal.

n = 11;
D = sparse(1:n,1:n,-4*ones(1,n),n,n);
full(D);
E = sparse(2:n,1:n-1,ones(1,n-1),n,n);
E(11,10)=2;
full(E);
F = sparse(1:n-1,2:n,ones(1,n-1),n,n);
F(1,2)=2;
full(F);
S = E+D+F;
A=full(S)

temp = repmat({S}, 1, 11);
result = blkdiag(temp{:});
