1. Put the coded message into the columns of a matrix, K, where column 1=
[19, 5, 14], column= [4, 27, 8], and column 3= [5, 12, 16], respectively.
Using the following integer coding matrix N, where column 1= [1 2 2],
column 2= [1 3 2], column 3= [2 5 3]. Compute the product NK= S?
The coded message S is transmitted, then received and decoded by
multiplying by the inverse of the coding matrix, namely, computing N-1S.
