In this paper we consider the solution of linear least squares problems min x Ax -b 2 2 where the matrix A โ R mรn is rank deficient. Put p = min{m, n}, let ฯ i , i = 1, 2, . . . , p, denote the singular values of A, and let u i and v i denote the corresponding left and right singular vectors. Then
