翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Parameter ： ウィキペディア英語版 Parameter A parameter (from the Ancient Greek παρά, "para", meaning "beside, subsidiary" and μέτρον, "metron", meaning "measure"), in its common meaning, is a characteristic, feature, or measurable factor that can help in defining a particular system. A parameter is an important element to consider in evaluation or comprehension of an event, project, or situation. ''Parameter'' has more specific interpretations in mathematics, logic, linguistics, environmental science, and other disciplines.〔("Parameter" ) in TheFreeDictionary.com.〕 ==Mathematical functions== Mathematical functions have one or more arguments that are designated in the definition by variables. A function definition can also contain parameters, but unlike variables, parameters are not listed among the arguments that the function takes. When parameters are present, the definition actually defines a whole family of functions, one for every valid set of values of the parameters. For instance, one could define a general quadratic function by declaring :$f(x)=ax^2+bx+c$; here, the variable ''x'' designates the function's argument, but ''a'', ''b'', and ''c'' are parameters that determine which particular quadratic function is being considered. A parameter could be incorporated into the function name to indicate its dependence on the parameter. For instance, one may define the base ''b'' of a logarithm by :$\backslash log\_b(x)=\backslash frac$ where ''b'' is a parameter that indicates which logarithmic function is being used. It is not an argument of the function, and will, for instance, be a constant when considering the derivative $\backslash textstyle\backslash log\_b\text{'}(x)$. In some informal situations it is a matter of convention (or historical accident) whether some or all of the symbols in a function definition are called parameters. However, changing the status of symbols between parameter and variable changes the function as a mathematical object. For instance, the notation for the falling factorial power :$n^=n(n-1)(n-2)\backslash cdots(n-k+1)$, defines a polynomial function of ''n'' (when ''k'' is considered a parameter), but is not a polynomial function of ''k'' (when ''n'' is considered a parameter). Indeed, in the latter case, it is only defined for non-negative integer arguments. More formal presentations of such situations typically start out with a function of several variables (including all those that might sometimes be called "parameters") such as :$(n,k)\; \backslash mapsto\; n^\{\backslash underline\{k\}\}$ as the most fundamental object being considered, then defining functions with fewer variables from the main one by means of currying. Sometimes it is useful to consider all functions with certain parameters as ''parametric family'', i.e. as an indexed family of functions. Examples from probability theory are given further below. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parameter」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
