A simple method: given a real antisymmetric matrix, its Schur decomposition yields the canonical form. Then the Pfaffian can be easily read off.

    But the basis may be reordered resulting in a wrong sign. So one has to take the determinant of the transformation matrix in order to determine the sign.
