Linear Least Squares Problems Solutions in the Lighthouse

Li-Yin Young, University of Colorado Boulder

Abstract

Linear least squares problems are commonly applied in computations for observational and experimental science. Using LAPACK functions is an efficient way to solve linear least squares problems, but LAPACK has so many functions and routines available that can overwhelm a non-expert user. The challenge for developing the Lighthouse taxonomy which is designed for searching available software and routines to solve numerical problems is finding the correct routines and then optimizing the implementation. LAPACK software packages can be connected with the Lighthouse interface so that optimum orthogonal solutions are provided for users' specific needs.
