There exist programs for the numerical computation of the Pfaffian on various platforms (Python, Matlab, Mathematica) (Wimmer 2012).The Pfaffian is an invariant polynomial of a skew-symmetric matrix under a proper orthogonal change of basis. As such, it is important in the theory of characteristic … See more In mathematics, the determinant of a skew-symmetric matrix can always be written as the square of a polynomial in the matrix entries, a polynomial with integer coefficients that only depend on the size of the matrix. The … See more Pfaffians have the following properties, which are similar to those of determinants. • Multiplication of a row and a column by a constant is equivalent to multiplication of the Pfaffian by the same constant. • Simultaneous interchange of two different rows and … See more • Determinant • Dimer model • Hafnian • Polyomino See more $${\displaystyle A={\begin{bmatrix}0&a\\-a&0\end{bmatrix}}.\qquad \operatorname {pf} (A)=a.}$$ See more Let A = (ai,j) be a 2n × 2n skew-symmetric matrix.
