5. Continuity of eigenvalues Suppose we drop the mean zero
... Jn is the matrix of all ones). The relevant question is how the ESD changes under such perturbations of the matrix. We prove some results that will be used many times later. We start with an example. Example 27. Let A be an n × n matrix with ai,i+1 = 1 for all i ≤ n − 1, and ai, j = 0 for all other ...
