利用随机矩阵的特性及不等式的性质,讨论了n阶随机矩阵的范数,获得了随机矩阵1-范数,2-范数,∞-范数及p-范数的不等式,且给出了1-范数,2-范数及p-范数达到界值的充分必要条件,为随机矩阵的应用奠定了数学基础.
The norm of stochastic matrix by using the characteristics of stochastic matrix and the properties of inequality is studied.The bounds of ∞-norm,1-norm,2-norm and p-norm about stochastic matrix are obtained and the sufficient and necessary conditions are given when those bounds are attained.Consequently,these results can establish the mathematics foundation for the application of stochastic matrix.
