1. (4 pts)Let The message shown on the next page was encoded with matrix B. You need to decode the message with the aid of your graphing calculator since matrix B is a large matrix, no row operations should be done for this problem. Follow these steps: enter two appropriate matrices in your calculator, you need to determine which ones, explain which ones you used » find the inverse matrix of B multiply two appropriate matrices, you need to determine...
You are wanting to communicate secret messages with your friend, and you choose to do this with matrices. The encoding matrix that you choose to use is 2 -2 -1 6 You use the following key to convert your message into a string of numbers, where "O" is used as a placeholder where required. A B C D EF G H IJ K L M 10 2 11 24 19 5 25 20 3 7 16 6 14 N O...
Cryptography, the study of secret writing, has been around for a very long time, from simplistic techniques to sophisticated mathematical techniques. No matter what the form however, there are some underlying things that must be done – encrypt the message and decrypt the encoded message. One of the earliest and simplest methods ever used to encrypt and decrypt messages is called the Caesar cipher method, used by Julius Caesar during the Gallic war. According to this method, letters of the...
Question 1: a) Encode the following data using the JPEG run length encoding: 67 19 6 4 8 2 0 0 0 5 0 2 3 0 0 6 2 2 0 4 0 0 1 0 0 0 0 0 0 0 0 0 0 b) Decode the following sequence, which has been encoded by the same run length encoding described in part (a): 27 0 12 0 14 0 5 0 19 0 13 0 9 0 8...

Write a c++ program: Many mathematical problems require the addition, subtraction, and multiplication of two matrices. Write an ADT Matrix. You may use the following class definition: const int MAX_ROWS = 10; const int MAX_COLS = 10; class MatrixType { public: MatrixType(); void MakeEmpty(); void SetSize(int rowsSize, int colSize); void StoreItem(int item, int row, int col); void Add(MatrixType otherOperand, MatrixType& result); void Sub(MatrixType otherOperand, MatrixType& result); void Mult(MatrixType otherOperand, MatrixType& result); void Print(ofstream& outfile); bool AddSubCompatible(MatrixType otherOperand); bool MultCompatible(MatrixType otherOperand);...
