AlgMatrixLSQR.c File Reference

Provides functions for solving matrix equations using LSQR. This software is based on lsqr.c, a C version of LSQR derived by James W. Howse jhows.nosp@m.e@la.nosp@m.nl.go.nosp@m.v from the Fortran 77 implementation of C. C. Paige and M. A. Saunders. In most cases the extensive comments from Howse's lsqr.c have been preserved with little change. More...
