The Gram–Schmidt algorithm has the disadvantage that small imprecisions in the calculation of inner products accumulate quickly and lead to effective loss of orthogonality. Alternative ways to obtain a QR-factorization are presented below on some examples. They are based onThe Gram-Schmidt process treats the variables in a given order, according to the columns in X. We start with a new matrix Z consisting of X [,1]. Then, find a new variable Z [,2] orthogonal to Z [,1] by subtracting the projection of X [,2] on Z [,1]. Continue in the same way, subtracting the projections of X [,3] on the previous columns, and so ...Example: rotation by θ in R2 is given by ... • to check if b ∈ span(a1,...,ak): apply Gram-Schmidt to [a1 ··· ak b] • staircase pattern in R shows which columns of A are dependent on previous ones works incrementally: one G-S procedure yields QR factorizations ofThe Gram-Schmidt process.

In this case, it means that p 0;:::;p k span the same space as 1;x;:::;xk. That is, the p 0;:::;p k polynomials are an orthogonal basis for all polynomials of degree k or less. These polynomials are very special in many ways.
