In mathematics, particularly linear algebra and numerical analysis, the Gram–Schmidt process is a method for orthonormalizing a set of vectors in an inner product space, most commonly the Euclidean space R equipped with the standard inner product. The Gram–Schmidt process takes a finite, linearly … See more We define the projection operator by where $${\displaystyle \langle \mathbf {v} ,\mathbf {u} \rangle }$$ denotes the inner product of the vectors v and u. This operator projects the vector v orthogonally onto the line … See more Euclidean space Consider the following set of vectors in R (with the conventional inner product) Now, perform … See more The following MATLAB algorithm implements the Gram–Schmidt orthonormalization for Euclidean Vectors. The vectors v1, ..., vk (columns of matrix V, so that V(:,j) is … See more Expressed using notation used in geometric algebra, the unnormalized results of the Gram–Schmidt process can be expressed as See more When this process is implemented on a computer, the vectors $${\displaystyle \mathbf {u} _{k}}$$ are often not quite orthogonal, due to See more The result of the Gram–Schmidt process may be expressed in a non-recursive formula using determinants. where D0=1 and, for j ≥ 1, Dj is the Gram determinant Note that the expression for uk is a "formal" … See more Other orthogonalization algorithms use Householder transformations or Givens rotations. The algorithms using Householder transformations are more stable than the stabilized Gram–Schmidt process. On the other hand, the Gram–Schmidt … See more
