coordinate vector


Let V be a vector spaceMathworldPlanetmath of dimensionPlanetmathPlanetmath n over a field K.  If  (b1,,bn)  is a basis of V, then any element v of V can be uniquely expressed in the form

v=ξ1b1++ξnbn

with  ξ1,,ξnK.  The n-tuplet (http://planetmath.org/OrderedTuplet)  (ξ1,,ξn) is called the coordinate vector of v with respect to the basis in question.  The scalars ξi are the coordinates (or the components of v).

It’s evident that the correspondence

v(ξ1,,ξn)

provides a linear isomorphism between the vector space V and the vector space formed by the Cartesian product Kn.
