Exercise 3.1 Can you think of any 2x2 matrices D for which CD - DC for all 2x2 matrices C? Give 2 different examples of such matrices D We can do other things with matrices as well. Among things to try are: A-(Subtracts two matrices.) 2A(Multiplies matrix A by a scalar 2.) A"3 (Raises the matrix A to the third power, i.e., multiplies A by itself three times.) > A. *B Multiplies the corresponding entries of the matrices together. We will not be using this command, but it is nice to know.) rref (A) (Gives the reduced row echelon form of A.) (Gives the transpose of A, sometimes written as AT) where A and B are the same matrices defined in the above example
