split()

template<Rank irank>

Tensor<irank + 1> syten::MPS::TEBD::split ( Tensor< irank > const &  itensor, MergeConfig const &  bases, int const  split_at = irank  )

inline

Takes a Tensor with rank irank and splits the leg with index split_at into two legs with indices split_at and split_at+1.

All indices greater than split_at will be shifted by 1.

Parameters

[in]	itensor	Tensor of rank \( irank \)
[in]	bases	merge configuration (from merge function)
[in]	split_at	where to split at

Returns

split tensor
