对幂等矩阵的研究

A research on idempotent matrix

在实数范围内研究幂等矩阵.给出幂等矩阵的定义,指出幂等矩阵的一些应用.罗列并证明了幂等矩阵的性质,对部分性质有更深层次的描述,从多个角度深入研究了与幂等矩阵有关的结论,在适当的地方附有例题,使得抽象内容变得容易理解.

This is a summary of research within the real number on idempotent matrix. Giver a definition of idempotent matrices, meanwhile the author lists and proves the nature of idempotent matrix . As for part of the features of idempotent matrix there is a study in- depth. When it comes to the conclusion of idempotent matrix there is a careful study from various angles with appropriate examples in the right places, which makes abstract content become easier to understand.
