[petsc-users] SLEPc: Setting options for mass matrix KSP in generalised eigenvalue problem

[Cotter, Colin J via petsc-users]

Dear PETSc mailing list,

  A SLEPc question, sorry if this is obvious and I missed something.


How do I set the KSP for the mass matrix M in the generalised eigenvalue problem

(I'm looking for the eigenvalue with largest magnitude)


Ax = lambda*Mx


?

I can only find how to set the KSP for a spectral transform.


(I'm actually using slepc4py)


all the best
