While this LGMRES looks nice, it's for numpy dense, not scipy.sparse matrices like scipy.sparse.lgmres.

Eigen does sparse too, https://eigen.tuxfamily.org/dox/group__TutorialSparse.html
but translating dense code to scipy-compatible sparse code looks ... SMOP.

Also, do you know of difficult test cases for *GMRES ?
Thanks, cheers
