[petsc-users] SLEPc Bogus eigenvalues for large -eps_nev

[Vijay Gopal Chilkuri]

oups sorry, I send you a smaller one (540540) this should finish in a few
minutes.

It requires the same makefile and irpf90.a library.
so just replace the old problem.c file with this and it should compile.

Thanks again,
 Vijay
