Updating QR factorization procedure for solution of linear least squares problem with equality constraints

Updating QR factorization procedure for solution of linear least squares problem with equality constraints

Abstract In this article, we present a QR updating procedure as a solution approach for linear least squares problem with equality constraints. We reduce the constrained problem to unconstrained linear least squares and partition it into a small subproblem. The QR factorization of the subproblem is...
