I have a quick question. Petsc can be configured with complex number. can KSP then be used to solve linear equations of complex number, that is, both the matrix elements and solutions are complex, directly without separation real and imaginary parts?

Yes. Not all solvers make sense in this mode, but some do.



Thank you very much.
