![]() ![]() ![]() What did i learn: i chose this article because its very simple and useful.It helps me text message others in a simpler way and in a fast way.I liked it and i can use it on daily bases. Requires understanding of matrices and deter. A Matrix Code uses mathematics to encode a message in groups of letters instead of one letter at a time. Its a bit easier than the Binary code computers th. ZC−1 = 19 19 14 /12 15 11/ 8 11 6 1 1 0/ 0 0 1 /1 2 0 = Computers and computer programmers use hexadecimal code (base sixteen) to communicate sometimes. If we multiply the matrices C−1 and Z in the opposite order, we Since the matrix multiplication is not commutative, it is necessary to keep the order of We put the text ”BILA KOCKA” (a white cat) into the matrix A: Let the following table and the matrix C be given:Ī B C D E F G H I J K L M N O P Q R S T U V W X Y ZĨ 7 5 13 9 16 18 22 4 23 11 3 21 1 6 15 12 19 2 14 17 20 25 24 10 ![]() To encode the text the matrix A can be multiplied by the matrix C for example on the The rest of the matrix can be filled with zero elements. In the case that the number of letters is lower than the number of elements of the matrix A, The text as a sequence of numbers will be organized into a square matrix A To encode a short message a number can be assigned to each letter of the alphabet according
