Normwise condition numbers of the indefinite least squares problem with multiple right-hand sides

Blog Article

In this Knock Boxes paper, we investigate the normwise condition numbers of the indefinite least squares problem with multiple right-hand sides with respect to the weighted Frobenius norm and 2-norm.The closed formulas or upper bounds for these condition numbers are presented, which extend the earlier Ball - Accessories - Sunglasses work for the indefinite least squares problem with single right-hand side.Numerical experiments are performed to illustrate the tightness of the upper bounds.
