rearrange()

template<typename IndexType , Rank irank>

Tensor<irank> syten::MPS::TEBD::rearrange ( Tensor< irank > const &  itensor, std::array< IndexType, irank > const &  indices  )

inline

Simply change the indicces (labels) of the legs.

Example: {3,2,1} switches the labels 1 and 3 between the respective legs.

Parameters

[in]	itensor	Tensor of rank \( irank \)
[in]	indices	vetor of new indices in form of a product specifier

Returns

new, rearranged tensor
