A Technique for Orthogonalization

Roger Fletcher

Open publisher page 18 citations

Abstract

An alternative to the Gram—Schmidt process is deseribed for carrying out orthogonalization of a given vector with respect to a given set of vectors. The technique is especially advantageous for problems in which the number of vectors in the set is likely to be both increased and decreased. A generalization to orthogonality with respect to a symmetric positive definite matrix is also deseribed.
