This is still a work in progress version of BiCGStab(ℓ). It is based on the original article, uses BLAS and includes left preconditioning.

At the moment I don't think it is completely necessary to implement the improvements from the papers. The thing is there is no standard implementation of BiCGStab(ℓ) and there's a lot of freedom.
The current implementation works fine for moderate values of
