An ordered arrangement of data items. A vector is a one dimensional array; a matrix is a two-dimensional array. Arrays are used in myriad applications from basic database processing to scientific simulation. Most programming languages support arrays by providing indexes into the data.
A vector space is defined as a set of vectors, a set of scalars, and a scalar multiplication operation that takes a scalar k and a vector v to another vector k v. For example, in a coordinate space, the scalar multiplication yields. In a (linear) function space, kÆ is the function x â¦ k (Æ (x)).
