The uncoded row matrices for a given message and hence encode the message.
Answer to Problem 137CR
The uncoded row matrices are-
The encoded message is given by the following array of numbers-
Explanation of Solution
Given: The message is LOOK OUT BELOW. And the given encoding matrix is-
Concept Used: In cryptography, each letter starting from A to Z are assigned number 1-26 respectively and blank space is assigned to 0. As a result, any message can be partitioned and converted into an array of numbers from which groups of three numbers can be used to produce matrices of order
Calculations: The given message is LOOK OUT BELOW. Partitioning the message (including blank spaces) into groups of three produces the following uncoded row matrices.
L O O K O U T B E L O W
The encoding matrix is
The coded matrices are obtained by multiplying each uncoded matrix with the encoding matrix. Hence, the required coded matrices are-
Finally, removing the brackets and writing the coded matrices in an array gives the required coded message which is-
