 Let V be a vector space with dim(V) = n and an ordered basis E := [x1,... .,xn].Let
 F:=[y1 , Yn] be the ordered orthonormal basis generated from basis E by applying the Gram- Schmidt Orthogonalization Process. For any62fb154e0d7e2.jpg denote the coordinate vectors of v with respect to bases E and F, respectively. Let T denote the transition matrix from basis E to basis F. Let L :62fb157462ec5.jpg, i.e. L is a linear operator mapping V into itself, and suppose that62fb159da9e1a.jpg
 Let's denote the matrix representation of L with respect to basis E by A.
