[petsc-users] Generalized eigenvalue problem using quad precision

[Santiago Andres Triana]

Dear all,

A rather general question, is there any possibility of solving a
complex-valued generalized eigenvalue problem using quad (or extended)
precision when the 'B' matrix is singular? So far I have been using MUMPS
with double precision with good results but I require eventually extended
precision. Any comment or advice highly welcome. Thanks in advance!
