dc.description.abstract	In this paper, a method to construct tridiagonal almost strictly sign regular (ASSR) matrices is presented. Moreover, we study the necessary conditions for this construction and we provide a characterization of an ASSR n × n matrix in terms of the sign of n minors of it.	spa
