Vector

A quantity possessing both magnitude and direction, typically represented as an ordered set of numerical components — an arrow from an origin to a point, or a column of coordinates. Vectors add and scale according to simple, consistent rules, which is what makes them useful well past physical space and velocity, as the basic representation for color, control data, or any other multi-dimensional quantity that needs to be combined or transformed as a single object. A vector is a specific, structured case of the more general tuple.
