Cryptography and Matrices. Cryptography $($Coded messages$)$ has a basis in matrix algebra. Consider a "Message" matrix $M,$ a crypto "Key" matrix $K,$ and an "Encrypted message" matrix $E$ which can result from the matrix multiplication of $M$ and $K$ :

$M*K=E$

$2$a$.$ Problem: If the "Key" matrix $K$ is given as indicated below, use the row operations method to determine the inverse matrix $K^{-1}.$

Appendix

$375$

$K=([-1,0,1],[2,3,4],[2,4,5])$

Once an encrypted message $E$ is delivered to the recipient, it can be decoded by multiplying by the inverse key matrix $K^{-1}$ applied on the right half of each side of the equations, yielding:

$M*K*K^{-1}=M*I=M=E*K^{-1}$

With this knowledge, and supplied with the following inputs as assumed "known values":

a "Key" matrix $K$ and its inverse $K^{-1}$

a code "Translation" matrix $T($to translate numbers into corresponding letters and spaces$)$ given by:

Write a computer code to decode and translate the messages $E$#$1$ and E#$2$ using matrix multiplication methods to accomplish $(E.K^{-1}),$ assuming that $K^{-1}$ is already a known provided from above, to determine MHI and $M$#$2.$ What do the messages say?

$2$c$.$ Problem: If the "Key" matrix $K$ is given as indicated below, use the row operations method to determine the inverse matrix $K^{-1}.$

$K=([4,9,2],[3,5,7],[8,1,6])$
