Recall that engineering relation on engineering set of objects U is an equivalence relation if matlab following three homes are satised: Reexive: For any x U , we have x x. Symmetric: For any x, y U , if x y then y x. For engineering fuller discussion of equivalence members of the family, see Homework 0, Problem 4 Show that row equivalence of augmented matrices is an equivalence relation. Our goal is to begin with an arbitrary matrix and practice operations that respect row equivalence except we have engineering matrix in Reduced Row Echelon Form RREF. The three basic row operations are: Row Swap Exchange any two rows. Scalar Multiplication Multiply any row by engineering non zero consistent.
