实幂等矩阵的性质探讨

Discuss a Properties of Real Idempotent Matrix

实幂等矩阵的性质在线性代数中有一些结论,文章对实幂等矩阵在和、差、积方面的性质进行了一些推广,并得出其成立的充要条件。

The line algebra has got the extensive application in many realms,while resolving actual prob - lems the matrix method is important.Some properties of real idemportent matrix have been discussed in this paper,so that we can use it in resolving actual problems.
