Created by Sal Khan. Questions Tips & Thanks Want to join the conversation? Sort by: Top Voted Glen Gunawan 12 years ago What exactly IS an orthonormal basis? Is it the basis of V as well? The Gram–Schmidt orthonormalization process is a procedure for orthonormalizing a set of vectors in an inner product space, most often the Euclidean space R n provided with the standard inner product, in mathematics, notably linear algebra and numerical analysis. The QR decomposition (also called the QR factorization) of a matrix is a decomposition of a matrix into the product of an orthogonal matrix and a triangular matrix. We’ll use a Gram-Schmidt process to compute a QR decomposition. Because doing so is so educational, we’ll write our own Python code to do the job. 4.3.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 {(1, − 1, 1), (1, 0, 1), (1, 1, 2)} . Gram-Schmidt & Least Squares .
