unprime() [1/2]

STensor & syten::STensorImpl::STensor::unprime	(	SBasisId const &	which,
		std::int8_t	value = 1
	)		&

Decreases the prime-level of the specified basis.

Remarks

This function is autodifferentiable except if the tensor network is incomplete and the downstream adjoint does not have a basis which.

This is the function overload for lvalues, which produces an lvalue reference.
