We can encode a message by assigning the numbers 1 - 26 to the letters a - z of the alphabet, respectively, and assigning 27 to a blank space. To further encode a message, we can use an encoding matrix A to convert these numbers into new pairs or triples of numbers. Use matrix A to encode the given message.Convert "I love you" from letters to numbers. Use pairs of those numbers, in order, to create 2 × 1 matrices, and multiply 
times those matrices to encode the message "I love you" into pairs of coded numbers. Combine the pairs of numbers to give the encoded numerical message.
