unfold_s8_to_s1#

unfold_s8_to_s1(eri, *, validate=True)[fuente]#

Unfolds an 8-fold symmetric tensor to 1-fold symmetries (4-dimensional).

Parámetros:
  • eri (Tensor | ndarray | SparseArray) – the 1-dimensional tensor to unfold.

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

Devuelve:

A 1-fold symmetric tensor.

Muestra:

ValueError – if eri is not 1-dimensional.
