openfermion.ops.antisymmetric_canonical_form
Compute the canonical form of an antisymmetric matrix.
openfermion.ops.antisymmetric_canonical_form(
antisymmetric_matrix
)
The input is a real, antisymmetric n x n matrix A, where n is even.
Its canonical form is::
A = R^T C R
where R is a real, orthogonal matrix and C has the form::
[ 0 D ]
[ -D 0 ]
where D is a diagonal matrix with nonnegative entries.
