In the teaching of linear algebra,we can observe,understand,mine and interpret the rich meaning of matrix operations by using the knowledge of set and mapping,variables and functions,and variable substitution.Without learning abstract linear space and linear mapping,we can show the deep motivation of introducing the concept of matrix similarity from the perspective of mapping and variable substitution.
