[petsc-users] Real data structure with complex build

Hi,

Is there a way to define the Mat(s) and Vec(s) to be real while working
with a complex build of PETSc? I'm asking because part of my problem is
real while the other part is complex. SO I'll be able to gain some
performance and reduction in memory if I can specify the PETSc data
structures in the real half of my code to be real.

Regards,
Bikash
