The Gram-Schmidt process in Matlab Yingwei Wang ∗ Department of Mathematics, Purdue University, West Lafayette, IN Some students said that they could not ﬁnd the so call “gschmidt” function in the Matlab in their computers. So I wrote this routine to achieve the Gram-Schmidt orthogonalization process in Matlab. function [Q,R]=gschmidt(V). Orthonormal basis and the Gram-Schmidt Process We can find an orthonormal basis for any vector space using Gram-Schmidt process. Such bases are very useful. Orthogonal projections can be computed using dot products Fourier series, wavelets, and so on from these. 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. Example Let V = R3 with the Euclidean inner product. We will apply the Gram-Schmidt algorithm to orthogonalize the basis f(1; 1;1);(1;0;1);(1;1;2)g.

The Gram-Schmidt orthogonalization process Let V be a vector space with an inner product. Suppose x1,x2,,xn is a basis for V. Let v1 = x1, v2 = x2. example of Gram-Schmidt orthogonalization Let us work with the standard inner product on ℝ 3 (dot product) so we can get a nice geometrical visualization.
