Some Common Properties Among Invertible Matrix,Adjoint Matrix and Inverse Matrix
Zhang Su · Journal of Xinzhou Teachers University · 2009
Discussed some common properties among invertible matrix,adjoint matrix and inverse matrix presented.Draw two important conclusions.Firstly,if any row(or column)sum of one matrix amongA,A*andA-1 is the same constant,then any row(or column)sum of another two matrixes is also the same constant.Secondly,let|A|=±1,if any element in one matrix amongA,A*andA-1 is integer,then any element in another two matrixes is also integer.
