## Summary The MF named `s` seems to be an unnecessary usage of memory as the residue `r` can fulfill its roles in the algorithm. This PR replaces `s` with `r` and `LinComb` with `Saxpy` as appropriate. ## Additional background This PR is part of a larger request to improve `solve_bicgstab` and `solve_cg`.
