Groups of letters DC, OD, EZ become the groups of values (3,2), (14,3), (4,25). Eventually, we will end up with an expression in which each element in the first row will be multiplied by a lower-dimension (than the original) matrix. There are a number of methods and formulas for calculating the determinant of a matrix. For example, given two matrices, A and B, with elements ai,j, and bi,j, the matrices are added by adding each element, then placing the result in a new matrix, C, in the corresponding position in the matrix: In the above matrices, a1,1 = 1; a1,2 = 2; b1,1 = 5; b1,2 = 6; etc. We have done such complete and thorough testing of the code behind this page that we are confident the results will be Hill cipher has been created in 1929 by Lester S.
