operator()() [3/3]

Tensor< 3 > const & syten::MPS::State::operator()	(	Index	site,
		int
	)		const

Returns a const reference to the tensor on that site.

Loads the tensor from disk if necessary, but does not store it there again if the reference is destroyed. site is 0-indexed. Due to being a const reference, the data file is not deleted from disk, allowing for efficiently saving the tensor again.

References data.
