[petsc-users] Slepc: Nonlinear eigenvalue problem

[Manav Bhatia]

Hi, 

   I am exploring the nonlinear eigenvalue problem solver in Slepc. 

   From the notes in "Sec 6.4: Retrieving the Solution”, it appears that if I expect to find complex eigenpairs then I must compile the library (and Petsc) with complex scalars. Is that correct? 

   Is there a way to include support for complex eigenpairs in a library complied with real scalars? 

Regards,
