ozaki_error_bound — DRIVE ozaki op

• Data kinds: matrix × matrix × scalar → matrix

• Call: import fullseye as fs; fs.ledger.ozaki_error_bound(A, B, n_slices: 'int') (to call the implementation directly, import ozakimm; ozakimm.ozaki_error_bound(A, B, n_slices: 'int'); from the registry, opsdrive.get("ozaki_error_bound"))

Usage

Guaranteed element-wise upper bound (a matrix) on the truncation error of matmul_ozaki(A, B, n_slices) (Ozaki-I).

切り捨ての残りと捨てた切れ端の組の和の上界で、最後の float64 の組み立ての丸め((s+1) u |A||B| 程度)は含めない。門では 26 万点余りの要素で破れ 0(PoC と tests)。並べ替えた和で計算するので、上界そのものも内側の順に依らない。
