    to find eigen value crieteria for parron frobinious theory

    thanks bur what is r here. i thought its dominant eigen value of matrix (i mentioned as 'int') . but if that is rue then there is no solution for which this (r<1) is satisfied. that is basic problem. if i dont found that then proceeding that paper wouldn't an easy task. while thanks\ this...
