. Let A be a nonnegative square matrix and B = DiADt where Di and Z>2 are diagonal matrices with positive diag- onal entries. Several proofs are known for the following theorem: If A is fully indecomposable then Di and Di can be chosen so that B is doubly stochastic. Moreover, Dx and D% are unique up to a scalar factor. It is shown that these results can be easily obtained by con-sidering a minimum of a certain rational function of several vari- ables.
