WebAn elementary permutation is a permutation that interchanges exactly two numbers. The determinant function is a function that associates with every square matrix, A, a number, denoted by det (A) or det A, such that det (A) is the sum of … All anti-diagonal matrices are also persymmetric. The product of two anti-diagonal matrices is a diagonal matrix. Furthermore, the product of an anti-diagonal matrix with a diagonal matrix is anti-diagonal, as is the product of a diagonal matrix with an anti-diagonal matrix. An anti-diagonal matrix is invertible if and only if the entries on the diagonal from the lower left co… the very best of patsy cline
