Cryptography matrix
WebRecall that the adjoint of a complex matrix is the complex conjugate composed with the transpose (see terminology section for details). Hence, because a complex number can be considered as a single-entry matrix, its transpose is itself, so that its adjoint is its complex conjugate. In polar form, the complex WebWe start by writing out the keyword as a matrix and converting this into a key matrix as for encryption. Now we must convert this to the inverse key matrix, for which there are several steps. The keyword written as a matrix. The key matrix (each letter of the keyword is converted to a number).
