	Contains all ‘smart’ tensor related classes and functions.
namespace	syten::STensorImpl::Autodiff
	Contains classes and functions to deal with autodifferentiation of STensor objects.

Typedefs
using	syten::STensorImpl::Autodiff::AdjointEvaluator = std::function< STensor(ComputeNode &node, Size input_number, STensorId const result_id)>
	Type of the input adjoint evaluator which can access the adjoints of all output values as well as the stored input and output tensors of the node to evaluate an output adjoint of an upstream node. More...
using	syten::AutodiffRescale = YesNo< struct _autodiffrescale >
	Whether or not to rescale the output adjoints during autodifferentiation. More...

	Type of a shared pointer to a compute node. More...
using	syten::STensorImpl::Autodiff::ComputeNodeWPtr = std::weak_ptr< ComputeNode >
	Type of a weak pointer to a compute node, used for the "downstream" direction. More...
using	syten::STensorImpl::Autodiff::STensorId = std::uint64_t
	Randomly-generated ID of an STensor, to be used during automatic differentiation. More...
