Abstract [en]

The objective of this paper is to consider a class of singular nonsym

metric matrices with integer spectrum. The class comprises generalized triangular matrices with diagonal elements obtained by summing the elements of the corresponding column. If the size of a matrix belonging to the class equals $n\times n$, the spectrum of the matrix is given by the sequence of distinct non-negative integers up to n-1, irrespective of the elements of the matrix. Right and left eigenvectors are obtained. Moreover, several interesting relations are presented, including factorizations via triangular matrices.
