Author:

Brualdi Richard A.

Abstract

Given an m × m m \times m symmetric nonnegative matrix A A and a positive vector R = ( r 1 , , r m ) R = ({r_1}, \cdots ,{r_m}) , necessary and sufficient conditions are obtained in order that there exist a diagonal matrix D D with positive main diagonal such that DAD has row sum vector R R .
