Let V be a vector space with dim(V) = n and an ordered basis E := [x
1,... .,x
n].Let
F:=[y
1 , Y
n] be the ordered orthonormal basis generated from basis E by applying the Gram- Schmidt Orthogonalization Process. For any

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 :

, i.e. L is a linear operator mapping V into itself, and suppose that

Let's denote the matrix representation of L with respect to basis E by A.
