It allows us to check whether vectors in a set are linearly independent. In this post, we understand how the Gram Schmidt process works and learn how to use it to create an orthonormal basis. 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.The term is called the linear projection of on the orthonormal set , while the term is called the residual of the linear projection.. Normalization. Another perhaps obvious fact that we are going to repeatedly use in the Gram-Schmidt process is that, if we take any non-zero vector and we divide it by its norm, then the result of the division is a new vector that has unit norm.QR decomposition writteninmatrixform: A = QR ,whereA 2 R m n,Q 2 R m n,R 2 R n: a 1 a 2 a n | {z } A = q 1 q 2 q n | {z } Q 2 6 6 4 r 11 r 12 r 1 n 0 r 22 r 2 n 0 0 r nn 3 7 7 5 | {z } R I Q TQ = I ,andR isuppertriangular&invertible I calledQR decomposition (orfactorization)ofA I usually computed using a variation on Gram-Schmidt procedure which is less sensitive …Gram-Schmidt With elimination, our goal was "make the matrix triangular".
