Explanation Given: The encoded matrix is, A = [ 1 2 2 3 7 9 − 1 − 4 − 7 ] The message is, ICEBERG DEAD AHEAD Approach: To convert the coded message into uncoded row matrices with n entries, convert the message into numbers and partition the number, The number that represents each letter is the place it comes in the alphabetical sequence starting from A as number 1 to Z as number 26. 0 is use for the blank space. To encode a message, multiply each uncoded row matrices with the encoded matrix. Calculation: Partition of the message into the group of three produces the uncoded row matrices, [ 9 3 5 ] [ 2 5 18 ] [ 7 0 4 ] [ 5 1 4 ] [ 0 1 8 ] [ 5 1 4 ] Multiply the matrix uncoded row matrix [ 9 3 5 ] with encoded matrix A . [ 9 3 5 ] [ 1 2 2 3 7 9 − 1 − 4 − 7 ] = [ 13 19 26 ] Multiply the matrix uncoded row matrix [ 2 5 18 ] with encoded matrix A . [ 2 5 18 ] [ 1 2 2 3 7 9 − 1 − 4 − 7 ] = [ − 1 − 33 − 77 ] Multiply the matrix uncoded row matrix [ 7 0 4 ] with encoded matrix A . [ 7 0 4 ] [ 1 2 2 3 7 9 − 1 − 4 − 7 ] = [ 3 − 2 − 14 ] Multiply the matrix uncoded row matrix [ 5 1 4 ] with encoded matrix A . [ 5 1 4 ] [ 1 2 2 3 7 9 − 1 − 4 − 7 ] = [ 4 1 − 9 ] Multiply the matrix uncoded row matrix [ 0 1 8 ] with encoded matrix A
