| Abstract: | This paper analyzes the method of calculating matrix rank with elementary transformation, utilizes the method and Gauss elimination to solve linear equations, analyzes the linear representation of vector group, the similarity principle of the linear relevance of vector group, and applies the method of calculating matrix rank with elementary transformation to the above three aspects. It can not only settle the solving and judgment of the three problems, but also integrate the learned knowledge, so as to lay a foundation for future learning. |
