Abstract
We study asymptotic and uniform properties of eigenvalues of a large class of real symmetric matrices that can be decomposed into the sum of a Toeplitz matrix and a Hankel matrix. In particular, we show that their properties are essentially driven by those of the Toeplitz part. A special subclass of structured matrices arising in an approximation problem is analyzed in detail.
