Gram schmidt example.

The Gram-Schmidt orthogonalization procedure is not generally recommended for numerical use. Suppose we write A = [a1:::am] and Q = [q1:::qm]. The essential problem is that if rjj ≪ ∥aj∥2, then cancellation can destroy the accuracy of the computed qj; and in particular, the computed qj may not be particularly orthogonal to the …

Of course, nobody wants to do things like the Gram Schmidt algorithm by hand. Fortunately, there’s a function for that. If we have vectors X,Y,Z, we can make a list L=[X,Y,Z], and perform Gram Schmidt with GramSchmidt(L). If you want your output to be an orthonormal basis (and not merely orthogonal), then you can use GramSchmidt(L,true).

I know what Gram-Schmidt is about and what it means but I have problem with the induction argument in the proof. Also, I have seen many proofs for Gram-Schmidt but this really is the worst as it confuses me so badly! :) Also, no motivation is given for the formula! This is one of the worst proofs that Axler has written in his nice book ...It is rather difficult to show the Gram–Schmidt procedure for the specific vectors utilized in our example. This being the case, Fig. 3.18 shows a more stylized conceptualization of the procedure. The pictures first show orthonormalization of the first two vectors in two dimensions and then orthonormalization of all three in three dimensions. 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.method is the Gram-Schmidt process. 1 Gram-Schmidt process Consider the GramSchmidt procedure, with the vectors to be considered in the process as columns of the matrix A.

For example hx+1,x2 +xi = R1 −1 (x+1)(x2 +x)dx = R1 −1 x3 +2x2 +xdx = 4/3. The reader should check that this gives an inner product space. The results about projections, orthogonality and the Gram-Schmidt Pro-cess carry over to inner product spaces. The magnitude of a vector v is defined as p hv,vi.
