We present a novel distributed QR factorization algorithm for orthogonalizing a set of vectors in a decentralized wireless sensor network. The algorithm is based on the classical Gram-Schmidt orthogonalization with all projections and inner products reformulated in a recursive manner. In contrast to existing distributed orthogonalization …studying the QR factorization we also looked at the modi ed Gram-Schmidt algorithm. That algorithm was less stable. However, it has the advantage that one get one col-umn of the unitary matrix Qone column at a time, i.e., the modi ed Gram-Schmidt algorithm can be stopped at any time and yields a partial set of orthonormal column vectors.

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.

Givens † Property 3.3 (Reduced Oct 7, 2019 · 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 previous qj ... Actually, I think using Gram-Schmidt orthogonalization you are only expected to find polynomials that are proportional to Hermite's polynomials, since by convention you can define the Hermite polynomials to have a different coefficient than the one you find using this method.
