摘要
重点探索了三幂等矩阵的性质.主要从矩阵乘积、线性变换和矩阵的秩等角度出发,将幂等矩阵的性质向三幂等矩阵推广,对三幂等矩阵的性质进行探究,得到了15个相关结论,并给出部分性质的详细推导过程.
Some properties are mainly explored about the triple idempotent matrix. Be generalized by the properties of the idempotent matrix,15 different conclusions of the triple idempotent matrix, about the sides of matrix product, linear transformation and rank of matrix, have been obtained by complete and detailed derivations.
