A new kind of weighted generalized inverse was defined to study indefinite least squares (ILS) problem and equality constrained indefinite least squares (ILSE) problem. By applying hyperbolic-QR factorization, the solutions to the two problems were obtained. Also the perturbation bounds of the solutions were derived.
