With this methodology we obtain a sequence of operators in the Levinson recurrences whose norms in geometric terms represent angles between subspaces. Additionally, under this geometric framework a LU decomposition for a block Toeplitz matrix is obtained.</p>}, number={4}, journal={Statistics, Optimization & Information Computing}, author={Marcano, José Gregorio and Morán, M.D.}, year={2019}, month={Dec.}, pages={748-758} }
