◆ 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]itensorTensor of rank \( irank \)
[in]basesmerge configuration (from merge function)
[in]split_atwhere to split at
Returns
split tensor
