So let's say I have the subspace V that is spanned by the vectors-- let's say we're dealing in R4, so the first vector is 0, 0, 1, 1. The second vector is 0, 1, 1, 0. And then a third vector-- so it's a three-dimensional subspace of R4-- it's 1, 1, 0, 0, just like that, three-dimensional subspace of R4.

Lecture 21: Gram-Schmidt ...Constructing an Orthonormal Basis: the Gram-Schmidt Process. To have something better resembling the standard dot product of ordinary three vectors, we need 〈 i | j 〉 = δ i j, that is, we need to construct an orthonormal basis in the space. There is a straightforward procedure for doing this called the Gram-Schmidt process. Step-by-Step Gram-Schmidt Example. Transform the basis x → 1 = [ 2 1] and x → 2 = [ 1 1] in R 2 to an orthonormal basis (i.e., perpendicular unit basis) using the Gram-Schmidt algorithm. Alright, so we need to find vectors R n and R n that are orthogonal to each other. First, we will let v → 1 equal x → 1, so.Gram-Schmidt Orthogonalization process Orthogonal bases are convenient to carry out computations. Jorgen Gram and Erhard Schmidt by the year 1900 made standard a process to compute an orthogonal basis from an arbitrary basis. (They actually needed it for vector spaces of functions.
