  (2)基本的な使用例

最低でも8桁確度まで数値積分を近似する:

Out[1]=1

ODEを解く際に,精度(相対誤差)を誤差制御の基準に使う:

Out[1]=1

相対誤差は小さい:

Out[3]=3

AccuracyGoalを指定しないと相対誤差はずっと大きくなる:

Out[4]=4

スコープ  (2)標準的な使用例のスコープの概要

収束基準を使って最小値を求める:

Out[2]=2

収束基準を使う:

Out[3]=3

機械精度では不可能な収束基準を使う:

Out[4]=4

作業精度を上げて収束させる:

Out[5]=5

高精度演算で微分方程式を解く:

Out[1]=1
Out[2]=2

AccuracyGoalPrecisionGoalを32桁の作業精度の半分で使う:

Out[3]=3

これは,NDSolveで使われる自動設定に相当する:

Out[4]=4
