摘　　要：文章研究诱导矩阵的数值半径.利用Schwarz不等式及可分解向量的内积与一般广义矩阵函数的关系,证明了诱导矩阵的数值半径不等式.The numerical radius of induced matrix was studied in this paper. By using the relations of Schwarz inequality and decomposable vector inner product in generalized matrix function, the inequality of numerical radius of induced Matrix was proved.
