名詞

Lua実行エラー 不可算名詞

(mathematical analysis, computing) A model for self-validated numerical analysis in which quantities are represented as affine combinations (called affine forms) of certain primitive variables that stand for sources of uncertainty in data or approximations made during computations.

日本語の意味

英語の意味

(mathematical analysis, computing) A model for self-validated numerical analysis in which quantities are represented as affine combinations (called affine forms) of certain primitive variables that stand for sources of uncertainty in data or approximations made during computations.

このボタンはなに？

When estimating errors in a nonlinear simulation, using affine arithmetic often yields tighter bounds than standard interval arithmetic.

非線形シミュレーションの誤差を推定するとき、アフィン形式に基づく算術を用いると、標準的な区間算術よりもより厳密な境界が得られることが多い。
