[petsc-users] How to use bicgstab2, bicgstab3 and bicgstab4

[Bao Kai]

Hi, all,

I am using petsc3.2 at the moment.

In the src directory, I found the ksp bcgsl which is intended for BICGSTAB(L).

My question is how to change the value of L.

Should I use -ksp_bcgsl_ell  to set different ell values?

Best Regards,
Kai
