## Abstract A sequence of leastβsquares problems of the form min~__y__~β₯__G__^1/2^(__A__^T^ __y__β__h__)β₯~2~, where __G__ is an __n__Γ__n__ positiveβdefinite diagonal weight matrix, and __A__ an __m__Γ__n__ (__m__β©½__n__) sparse matrix with some dense columns; has many applications in linear program
This article is concerned with iterative techniques for linear systems of equations arising from a least squares formulation of boundary value problems. In its classical form, the solution of the least squares method is obtained by solving the traditional normal equation. However, for nonsmooth boun
