concept uni20::DiagonalBlockStorage =  BlockTensorStorage<Storage> && requires {
  { Storage::stores_diagonal_blocks } -> std::convertible_to<bool>;
} && Storage::stores_diagonal_blocks

Detailed Description

BlockTensor storage whose stored numerical blocks are generalized diagonals.

Logical block presence remains the ordinary explicit BlockTensor key set. This refinement describes only the compressed numerical representation within each stored block.

Template Parameters

Storage

Candidate policy type.
