	Gram
		Gram is best remembered for the Gram-Schmidt orthogonalisation process which constructs an orthogonal set of from an independent one.
		Gram later published this work in the Journal für Mathematik and it proved to be of fundamental importance in the development of the theory of integral equations.
		The process seems to be a result of Laplace and it was essentially used by Cauchy in 1836.

	Schmidt
		Schmidt's interest in topology influenced Hopf and, in 1929, he was an examiner of Hopf's doctoral thesis.
		Schmidt published a two part paper on integral equations in 1907 in which he reproved Hilbert's results in a simpler fashion, and also with less restrictions.
		Schmidt arrived at the University of Berlin shortly after the death of Frobenius, who had jointly led the department with Schwarz.

	Generic Gram-Schmidt by Exact Division
		Given a vector space basis with integral domain coefficients, a variant of the Gram-Schmidt process produces an orthogonal basis using exact divisions, so that all arithmetic is within the integral domain.
		Zero-division is avoided by the assumption that in the domain a sum of squares of nonzero elements is always nonzero.

	Gram-Schmidt process - Wikipedia, the free encyclopedia
		In mathematics and numerical analysis, the Gram-Schmidt process of linear algebra is a method of orthogonalizing a set of vectors in an inner product space, most commonly the Euclidean space R
		The method is named for Jørgen Pedersen Gram and Erhard Schmidt, but is older, and to be found in the work of Laplace and Cauchy.
		In the theory of Lie group decompositions it is generalized by the Iwasawa decomposition.

	Gram-Schmidt
		For the process to succeed in producing an orthonormal set, the given vectors must be linearly independent.
		It does this by sequentially processing the list of vectors, generating a vector perpendicular to the previous vectors in the list.

	Talk:Gram-Schmidt process - Wikipedia, the free encyclopedia
		I was going to rewrite the process in terms of projections to clean it up a bit, but I'll probably stuff it up somewhere and be shouted at.
		This allows the process to work in fields where you cannot take square roots, such as the rationals.
		So, if you feel up to doing so, I think it'd clear up the process greatly.

	Parallel GMRES and Domain Decomposition
		It is well known that the performance of GMRES on a distributed memory platform suffers from the abundant amount of communication required in the modified Gram-Schmidt process.
		We show that the modified Gram-Schmidt processes can be performed without any communication to obtain orthogonal bases for these subspaces.
		In this talk we propose a generalization of GMRES in which the solution space is decomposed in a set of orthogonal subspaces.

	Citations: Solving Linear Least Squares Problems by Gram-Schmidt Orthogonalization - Bjorck (ResearchIndex)
		Modified Gram Schmidt (MGS) improves the numerical stability of the GS by orthogonalizing individual pairs of vectors rather than a vector against a block.
		Therefore, the Modified Gram Schmidt (MGS) method is preferred, which is stable with respect to rounding errors [4] However, in MGS the inner products should be calculated sequentially.
		The reader may refer to Bjorck s survey paper [2] where variants of the classical Gram Schmidt algorithm are discussed.

		Applying the Gram-Schmidt process, we let v_1 = [1, 1, 1] and compute [1, 0, 1] - (1 + 0 + 1)/(1 + 1 + 1) [1, 1, 1] = [1, 0, 1] - (2/3)[1, 1, 1] = [1/3, -2/3, 1/3] and take v_2 = [1, -2, 1].
		Applying the Gram-Schmidt process, let v_1 = a = [1, 1, 1], and a_2 = e_1, and we get a_2 - (a_2v_1)/(v_1v_1) v_1 = [2/3, -1/3, -1/3] so we take v_2 = [2, -1, -1].
		Again we apply the Gram-Schmidt process, letting v_1 = [1, -1, 1, 0, 0].

		The Gram-Schmidt process then results in a series of alternately even and odd functions which are proportional to the Legendre polynomials.
		The value 2 is repeated, requiring one to go through the Gram-Schmidt orthogonalization process to obtain an orthonormal basis.
		Gram-Schmidt orthogonalization was discussed with the example of polynomials in x on the interval -1 less than or equal to x less than or equal to +1.

	MATH2071: LAB #10: QR Factorizations
		The Gram Schmidt method can be thought of as a process which analyzes a set of vectors X, producing an "equivalent" (and possibly smaller) set of vectors Q which span the same space, have unit L2 norm, and are pairwise orthogonal.
		In the same way, the Gram-Schmidt process is actually carrying out a different factorization that will give us the key to other problems.
		Recall how the process of Gauss elimination could actually be regarded as a process of factorization.

		The basic idea of this process is a change of domain.
		This process takes a functions transform, which is a function that is continuous, to a linear combination of the transform.
		However, because the mathematics involved is beyond the scope of this paper, we will leave this process of minimizing error to the reader.

	Gram-Schmidt Process Question - Physics Help and Math Help - Physics Forums
		What will happen if this process is applied to a set of vectors {v1, v2, v3} where v1 and v2 are linearly independent, but v3 belongs to set Span(v1,v2).
		But, if j=Dim(V) where V was an arbitrary space, and vk was an element of span(v1,...vk-1) for kprocess would result in an orthonormal set which DOES not form a basis for V, it merely spans/forms a basis or some subset/space of V. BerkMath
		It does nothing to further the purpose of GS, however; it does not destroy it, so long as your original set does contain elements which lie outside the span of its companions.

		Recall the Gram-Schmidt orthogonalization process for obtaining an orthogonal basis for the span of a set of linearly independent vectors.
		All in all, it is not evident that such an approach will converge to anything at all; but if it does converge, the result is a Lovász-reduced basis.
		Note that the definition is sensitive to order: the same basis vectors in a different order may not form a Lovász-reduced basis.

		Abstract: The Gram-Schmidt orthonormalization process is a fundamental formula of analysis which is notoriously unstable computationally.
		The formulas for the error propagation are then used to produce a linear corrector for the basic Gram-Schmidt process, which shows significant improvement over both previous methods, but at the cost of slightly more computations.
		This report provides a heuristic analysis of the process, which shows why the method is unstable.

	Description of the Modified Gram-Schmidt Algorithm
		The Gram-Schmidt Algorithm is a process to convert a set of linearly independent vectors into an orthonormal set of vectors.
		As a demonstration of this, the Gram-Schmidt algorithm will be modified to avoid unfortunate cancellations of significant data.
		We have used it in this course as a good example of the qualitative impact of small errors in numerical analysis in vector based domains.
