We Can Encode a Message by Assigning the Numbers 1 $$A = \left[ \begin{array} { r c c } 4 & 2 & - 2 \\- 3 & 1 & 2 \\3 & - 2 & 1\end{array} \right]$$

question 143

Short Answer

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.
-Use the matrix A $$A = \left[ \begin{array} { r c c } 4 & 2 & - 2 \\- 3 & 1 & 2 \\3 & - 2 & 1\end{array} \right]$$ to encode the message "Thank you" into triples of numbers. Combine the triples
of numbers to give the encoded numerical message.
