It.The notion of two matrices being row-equivalent is an example of an equivalence relation we have been working with since the beginning of the course (see Exercise RREF.T11 ). Row-equivalent matrices are not equal, but they are a lot alike.We will illustrate these as we prove that similarity is an equivalence relation.
