change_fermionic_order()

STensor syten::STensorImpl::change_fermionic_order	(	STensor	in,
		ConstSpan< Index >	to_this
	)

Changes the fermionic order of the tensor to the specified ordering.

This multiplies the tensorblocks by the appropriate factors such that the ‘meaning’ of the tensor is the same as before.

Remarks

This is an AD-no-op and hence autodifferentiable.
