Matrix multiplication involves the multiplication of two matrices to produce a third matrix – the matrix product. This allows for the efficient processing of multiple data points or operations ...

Abstract: Developers are often limited to the use of low order matrix keys when the Hill cipher is embraced. This is due to the complexity of determining matrix inverses when high order matrices are ...

Abstract: In this paper, we study some structural properties of M-matrices and inverse M-matrices. Based on the UL and LU decompositions of an nonsingular tri-diagonal matrix, we get explicit formulas ...
