Write it here: Starting in the upper left corner and moving down the column and then to the next column, take the numbers from the secret message and write them along the top row of the grid. Please try again using a different payment method. Step 3. YouTube. We thus use the first matrix (A) to encode two characters at a time, and then use the inverse of the matrix to decode. That is, we swap the top left and bottom right numbers in the key matrix, and change the sign of the the top right and bottom left numbers. Because matrix codes are very difficult to decode (you need to be able to guess what the original matrix was, and then find its inverse), and sometimes people use coded messages to help them do illegal things. My code demonstrates a small part of it, like solving sets of many equations, finding connections between vectors, multiplying, adding matrixes, and more. Power of a matrix.
