Self inverse matrices
WebMar 24, 2024 · Matrices Matrix Types Hermitian Matrix A square matrix is called Hermitian if it is self-adjoint. Therefore, a Hermitian matrix is defined as one for which (1) where denotes the conjugate transpose. This is equivalent to the condition (2) where denotes the complex conjugate. Webtential of being self-invertible. In this new class of matrices, we obtain not only the MDS matrices with the least XOR gates requirement for dimensions from 3 43 to 8 8 in GF(2 ) and GF(28), but also involu-tory MDS matrices which was proven to be non-existence in the class of circulant matrices. To the best of our knowledge, the latter ...

WebAdding all the elements of a matrix to itself would be the same as multiplying every cell in the matrix by 2, or multiplying the matrix itself by 2. You don't need to worry about the dimensions lining up because you are adding the same matrix to itself, and then you would simply multiply every cell in the matrix by 2.
