摘要
适合条件 :M2 =M的矩阵M ,称为幂等矩阵 .首先用两种不同的方法建立了二阶幂等矩阵的表现定理 。
If the matrix M fits the condition M 2=M, it is called idempotent matrix.In this article,we first establish the expression theory when the order of matrix is two by using two different ways,and then make a description of the general idempotent matrix
