Webbof the Pfaffian of a matrix is equal to the determinant of the matrix, i.e., det(A) = Pf(A)2. Matrix A is called a centrosymmetric matrix if A = JAJ−1, where J is the anti-diagonal matrix whose anti-diagonal elements are one with all others being zero. If A = −JAJ−1, the matrix is said to be skew-centrosymmetric.
