fold_s1_to_s8

fold_s1_to_s8(eri, *, validate=True)

Folds a 4-dimensional tensor to 8-fold symmetries (1-dimensional).

Parámetros:

• eri (Tensor | ndarray | SparseArray) – the 4-dimensional tensor to fold.

• validate (bool) – when set to False, the requirements of eri are not validated.

Devuelve:

An 8-fold symmetric tensor.

Muestra:

• ValueError – if eri is not 4-dimensional.

• ValueError – if eri does not satisfy the permutational symmetries dictated by the chemist” convention for the ordering of two-body electronic integrals.

Tipo del valor devuelto:
