There are many ways to generate such a matrix. One possible way:

diagvalue = 5;
othervalue = 7;
diaglength = 10;
m = eye(diaglength) .* diagvalue + ~eye(diaglength) .* othervalue

Thank you, it works fine!

When d is "var(d_1^2)" and v is the vector added to the diagonal:

Result = repmat(d, n, n) + diag(v);
