  New preconditioners for least squares problems based on incomplete LU factorizations are presented.Two approaches are considered: computing an incomplete LU factorization of a suitable submatrix of the coefficient matrix,or to compute a pseudoinverse from an incomplete LU factorization and use it as preconditioner.
