is_trivial_order_a()

template<Rank rank>

bool syten::DenseProduct::is_trivial_order_a	(	std::array< Index, rank > const &	dims,
		std::array< int, rank > const &	c_a
	)

Returns true if the tensor as specified by its dimensions and contraction specifier does not have to be transposed to be usable in a TTGT-based tensor transposition if it is the first tensor to be contracted.
