Inverse properties of a class of pentadiagonal matrices related to higher order difference operators

Bakytzhan Kurmanbek, Yogi Erlangga, Yerlan Amanbek

This paper analyzes the convergence of fixed-point iterations of the form u = f(u) and the properties of the inverse of the related pentadiagonal matrices, associated with the four…

Inverse properties of a class of seven-diagonal (near) Toeplitz matrices

Bakytzhan Kurmanbek, Yogi Erlangga, Yerlan Amanbek

This paper discusses the explicit inverse of a class of seven-diagonal (near) Toeplitz matrices, which arises in the numerical solutions of nonlinear fourth-order differential equa…
