krylov-based iterative sparse solvers

Solvers

Systems of linear equations:

• bicg
• bicgstab
• cg
• cgs
• gmres
• lgmres
• minres
• gcrotmk
• qmr
• tfqmr

Constraints

• vectors are contiguous Fortran arrays
• routines must be interchangeable
• feature parity with scipy.sparse.linalg

Future ideas

• OpenMP for GPU parallelism
• verbose mode with formatted output
