zeroExpand()

template<Rank rank>

void syten::zeroExpand ( Tensor< rank > &  a, Index  which, Basis const &  basis, bool const  relaxed = false  )

inline

Zero-pads a tensor a along the specified leg which to contain the basis basis.

Parameters

[in,out]	a	tensor to be expanded in-place
[in]	which	tensor leg which is to be expanded
[in]	basis	expansion basis to match
[in]	relaxed	do not abort if expansion basis is smaller than current tensor basis
