Gram-schmidt orthogonalization

Feb 4, 2021 · where and are orthogonal. The vector can be interpreted as the result of removing the component of along . Gram-Schmidt procedure . The Gram-Schmidt procedure is a particular orthogonalization algorithm. The basic idea is to first orthogonalize each vector w.r.t. previous ones; then normalize result to have norm one. .

where Q is an orthogonal matrix (i.e. QTQ = I) and R is an upper triangular matrix. 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 Björck, Gram-Schmidt Orthogonalization: 100 Years and More, 2010. – slides 16 to 23 discuss the loss of orthogonality in classical GS and bounds in modified GS.

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. Gram-Schmidt to them: the functions q 1;q 2;:::;q n will form an orthonormal basis for all polynomials of degree n 1. There is another name for these functions: they are called the Legendre polynomials, and play an im-portant role in the understanding of functions, polynomials, integration, differential equations, and many other areas.

Proof. We will use induction to check that each is nonzero, is in the span of and is orthogonal to all preceding vectors: .

For any subspace of and basis for that subspace, the Gram-Schmidt algorithm produces an orthogonal basis for , which depends only on the ordering of the initial basis elements in .

Gram Schmidt can be modified to allow singular matrices, where you discard the projections of a previously-calculated linearly dependent vector. In other words, the vectors calculated after finding a linear dependent vector can be assumed to be zeros. Quá trình Gram–Schmidt.

On the other hand, the Gram-Schmidt process produces the j-th orthogonalized vector after the j-th iteration, while orthogonalization using Givens rotations produces all the vectors only at the end. This makes the Gram ...
