摘要
讨论坡矩阵(坡上的矩阵)的{1}-广义逆和{1,2}-广义逆,给出其存在的若干条件及结构定理,并指出它们与经典矩阵的{1}-广义逆和{1,2}-广义逆的若干差别.
The{1}-generalized inverses and{1,2}-generalized inverses of incline matrices(matrices on an incline)were discussed,and some conditions for existences of the{1}-generalized inverses and the{1,2}-generalized inverses and their structure theorems were given.Further,some differences between these incline matrices and classical matrices were shown,also.
