The crucial feature of the Gram-Schmidt process that we exploit here is that the first k vectors of its result span the same subspace as the first k vectors of its input for any k. A consequence of this is that the k th output vector is orthogonal to all previous output vectors. Obviously, this would not work with any basis.This is an implementation of Stabilized Gram-Schmidt Orthonormal Approach. This algorithm receives a set of linearly independent vectors and generates a set of orthonormal vectors. For instance consider two vectors u = [2 2], v= [3 1], the output of the algorithm is e1 = [-0.3162 0.9487], e2= [0.9487 0.3162], which are two orthonormal vectors.The Gram-Schmidt algorithm is powerful in that it not only guarantees the existence of an orthonormal basis for any inner product space, but actually gives the construction of such a basis.

If A is nonsingular, then this factorization is unique. There are several methods for actually computing the QR decomposition. One of such method is the Gram-Schmidt process. 1 Gram-Schmidt process

Sep 1, 2022 · The development of low-synch Modified Gram–Schmidt (MGS) and low-synch CGS2 was largely driven by applications that need stable, yet scalable solvers. Both MGS and CGS2 are stable orthogonalization schemes for a GMRES solver. Indeed, CGS2 produces an ɛ loss of orthogonality, which suffices for GMRES to converge.
