Detailed Description

template<std::size_t LhsRank, std::size_t RhsRank, std::size_t ContractedRank>
struct uni20::linalg::ContractionAxes< LhsRank, RhsRank, ContractedRank >

Canonical contracted and surviving axes for two fixed-rank operands.

Contracted pairs are ordered by the left operand axis. Surviving axes retain their original order. The corresponding output order is all surviving left axes followed by all surviving right axes.
