N=5;
C=sparse(zeros(N-1));
C([1 end])=C([1 end])+1;
B=speye(N-1);
B([1 end])=B([1 end])-1/2;
I have B and C matrices. I can form a blockdiagonal matrix such that C on the diagonal. As follows;
E0=speye(N);
E0=E0(1:end-1,1:end-1);
T2=kron(E0,C);
But I want to change the first and the last blocks with the matrix B.( In the first block and last block instead of C there should be B matrix.)
How can I do that? (N will be a variable so the size of the matrix will change according to the written N value.)

Why not use blkdiag() function?
T=blkdiag(B,C,B);
