We have encoded messages by assigning the letters of the alphabet the numbers 1-26, with a blank assigned the number 27, and by using an encoding matrix A that converts the numbers to the coded message. To decode any message encoded by A, we must find the inverse of A, denoted by A-1, and multiply A-1 times the coded message. Use this code and the given encoding matrix A to find the matrix that can be used to decode the given message.
The code matrix is . The message is 33, 132, 214, 22, 110, 203, 34, 132, 201.
