  • Abstract
    Condition numbers play an important role in numerical analysis. In this paper, we consider the condition number for the weighted linear least-squares(WLS) problems min with full-row rank as well as an explicit computable expression of the condition number for weighted linear least squares problem under the condition. The results extend the earlier works of some anthers.
