If S = {v1, v2, …, vn} is a basis for a vector space V, andv = c1v1 + c2v2 + ··· + cnvn is the expression for a vector v in terms of the basis S, then the scalars c1, c2, …, cn, are called the coordinates of v relative to the basis S. The vector (c1, c2, …, cn) in Rn constructed from these coordinates is called the coordinate vector of v relative to S; it is denoted by(v)S = (c1, c2, …, cn)RemarkCoordinate vectors depend not only on the basis S but also on the order in which the basis vectors are written.A change in the order of the basis vectors results in a corresponding change of order for the entries in the coordinate vector.
