Abstract: Here, inner bounds for the extreme eigenvalues of a real symmetric matrix are derived by using a two-dimensional subspace of Rn. The addition of a single parameter to the basis vectors and optimization thereof results in superior bounds, as compared to using fixed basis vectors. This is a rather simple procedure that is easily automated.
