Matrices provide methods for coding messages. Let the letters of the English alphabet be represented by the numbers 1, 2, 3, ., 26 as follows: A B C D E F G K M N Q R U V W Y 1 3 4 6 7 8 9. 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 We decide to code 2 x n messages by multiplying a message on the left by the following matrix: A = [{ ] GOOD For example, the message would be coded by LUCK E 12 21 3 15 15 74 135 45 631 11 43 78 24 37 Decode this message: 491 [66 85 94 50 54 27 [35 ||
