✦ Synopsis


Weakest linear conditions on the rows of a square matrix of arbitrary dimension to ensure that its determinant is positive are described and analyzed. In addition to strict diagonal dominance by rows with positive diagonal elements, we ®nd a new weakest set of conditions: the row mean being positive and larger than all the o-diagonal entries in that row. A complete classi®cation is provided for 3 Â 3 matrices.

Observer synthesis for linear positive systems is treated. The concept of observability of a linear positive system is defined and a characterization of observability is provided. An observable canonical form is proposed for a linear positive system with respect to an equivalent relation defined by
