Analytical Inversion of Tridiagonal Hermitian Matrices
Yuri R. Hakopian, Avetik H. Manukyan · Mathematical Problems of Computer Science · 2022
In this paper we give an algorithm for inverting complex tridiagonal Hermitian matrices with optimal computational efforts. For matrices of a special form and, in particular, for Toeplitz matrices, the derived formulas lead to closed-form expressions for the elements of inverse matrices.
