Using the matrix, it’s then easy to multiply severity times likelihood to get an impact score in the form of a number value. A risk that’s catastrophic and very likely would rank as a 25, whereas one that’s insignificant and very unlikely would rank as a one. It’s a simple and...
What is ab^{-1} matrix? A square matrix is called a permutation matrix if it contains the entry 1 exactly once in each row and in each column, with al other entries being 0. All permutation matrices are invertible. Find the inverse of the following permutation matrix \begin{bmat ...
The matrix appearing in (1) can then be written as , where is the matrix and is the (augmented) Gram matrix The matrix is a rank one matrix, and so is also. The Gram matrix factorises as , where is the matrix with rows , and thus has rank at most . Therefore the matrix in...
