If you use Maple for computations, include a printout of that as well. Explain in your own words how to use matrix multiplication to encode and decode messages. (This should be more than a couple of sentences!) Write the encoded row matrices of the indicated size for the given message. Then encode the message using the matrix A. Message: BEAM ME UP SCOTTY Row matrix size: 1X3 Encoding matrix: A=[2 1 4 3 1 3 -2 -1 -3] Find A^-1 and show how it decodes the message above
