由矩阵多项式的秩性质,给出广义m对合矩阵与(m,l)幂等矩阵的充要条件,推广并改进了m对合矩阵和m幂等矩阵的相应结论.
Based on the properties of the rank of the matrix polynomial, the necessary and sufficient conditions of generalized m involutory matrix and (m,l) idempotent matrix were obtained so as to generalize and improve the corresponding results of m involutory matrix and m-idempotent matrix.
