KeyMap

KeyMap[f,key1val1,key2val2,]

f を連想中のキーにマップし,f[key1]val1,f[key2]val2,を与える.

KeyMap[f]

式に適用可能なKeyMapの演算子形を表す.

詳細

  • f[keyi]の中に等しいものがあると,後で現れるものに関連する値が前に現れるものの値を置換する.
  • KeyMap[f][expr]KeyMap[f,expr]に等しい.
  • Parallelize[KeyMap[f,key1val1,key2val2,]]KeyMap[f,key1val1,key2val2,]をすべてのサブカーネルで並列に計算する. »
