There was and there will be. I had a package with bicgstab. I took it off line a while. I have been optimising the package and adding a lot of other Krylov methods. As soon as I think its ready (in a month or so) I will put it back online. The package will bring:
*Solvers for determined systems* - cg - bicg - cgs - bicgstab - bicgstabl - qmr - tfqmr - qmrcgstab - idr - gmres *Solvers for overdetermined systems* - cgls - lsqr - lsqmr
