ABSTRACT: Numeric algorithms for solving the linear systems of tridiagonal type have already existed. The well-known Thomas algorithm is an example of such algorithms. The current paper is mainly ...

SIAM Journal on Numerical Analysis contains research articles on the development and analysis of numerical methods including their convergence, stability, and error ...

In this paper Routh canonical form is derived for a general class of characteristic polynomials having roots with nonpositive real parts. This canonical form has real entries which are derived from a ...
