In Class Demonstration: The Change of Coordinate Matrix By Russell Blyth with(LinearAlgebra): Let V be a vector space of finite dimension, with bases B and B'. The change of coordinate matrix Q has columns which are the coordinate vectors for the vectors in B' relative to B.

Suppose T is the linear operator such that T(1,2,3) = (4,5,6), T(2,2,2) = (-1,-1,-1), and T(1,0,1) = (0,1,0). We will find the formula for T (in terms of the standard basis). Let B be the standard basis for R3, and let B' be the basis {(1,2,3),(2,2,2), (1,0,1)}. We write these bases as columns of the matrices B3 and B3p: B3 := <<1,0,0>|<0,1,0>|<0,0,1>>;

To do this we need to find the coordinates of the image of each basis vector relative to B'; these coordinate vectors then become the columns of the matrix of T relative to B'.
