mapping \mapping\ n. (Math.) A function such that for every element of one set there is a unique element of another set. Syn: map, correspondence. [WordNet 1.5]The Collaborative International Dictionary of English v.0.48:

Map \Map\, v. t. [imp. & p. p. Mapped; p. pr. & vb. n. Mapping.] To represent by a map; -- often with out; as, to survey and map, or map out, a county. Hence, figuratively: To represent or indicate systematically and clearly; to sketch; to plan; as, to map, or map out, a journey; to map out business. [1913 Webster] I am near to the place where they should meet, if Pisanio have mapped it truly. --Shak. [1913 Webster]WordNet (r) 3.0 (2006):

function mapping 1.(Or "map", "mapping") If D and C are sets (the domain and codomain) then a function f from D to C, normally written "f : D -> C" is a subset of D x C such that: 1. For each d in D there exists some c in C such that (d,c) is an element of f. I.e. the function is defined for every element of D. 2. For each d in D, c1 and c2 in C, if both (d,c1) and (d,c2) are elements of f then c1 = c2. I.e. the function is uniquely defined for every element of D. See also image, inverse, partial function. 2. Computing usage derives from the mathematical term but is much less strict. In programming (except in functional programming), a function may return different values each time it is called with the same argument values and may have side effects. A procedure is a function which returns no value but has only side-effects. The C language, for example, has no procedures, only functions. ANSI C even defines a type, void, for the result of a function that has no result. (1996-09-01)
