Normwise condition numbers of the indefinite least squares problem with multiple right-hand sides
In this 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 work for...
