Jorge Delgado, Héctor Orera, Juan Manuel Peña · Linear and Multilinear Algebra · 2021
Tridiagonal Toeplitz P-matrices, M-matrices and totally positive matrices are characterized. For some classes of tridiagonal matrices and tridiagonal Toeplitz matrices, it is shown that many algebraic computations can be performed with high relative accuracy.
