rows() [2/2]

template<Rank rank>

Index syten::Deparallelise::rows ( Tensor< rank > const &  in, Index const  uncombinedLeg, Tensor< 2 > &  t, Tensor< rank > &  p  )

inline

Row-based deparallelisation.

Parameters

[in]	in	input tensor to decompose into in → t p
[in]	uncombinedLeg	leg of in/p which is not combined and at which t attaches
[out]	t	output tensor with rank 2
[out]	p	output tensor with same rank as in

Returns

the number of discarded vectors
