NonPositiveReals
詳細

- x が数量なら,x∈NonPositiveRealsは即座に評価される.
- Simplify[expr∈NonPositiveReals,assum]を使って,式が与えられた仮定の下で非正実数に対応するかどうかを判定することができる.
- (x1x2…)∈NonPositiveRealsおよび{x1,x2,…}∈NonPositiveRealsは,すべての xiが非正実数かどうかを調べる.
- NonPositiveRealsは,StandardFormとTraditionalFormでは
として出力される.タイプセットした形は
npreals
を使って入力できる.
