Dear PETSc Developers,<br><br>Recently, I am trying to find some complex number-based solvers and preconditioners. However, it is difficult to find a general framework to include some solvers and preconditioners. Trilinos is developing a package, komplex, to use the real-number-based solver to solve complex number -based problem. I don't know whether PETSc wants to develop such the function for complex number-based problem. I think it will significantly increase the application range of PETSc. After all, in PETSc, lots of solvers and preconditioners have been developed. Thanks a lot.<br>
<br>Regards,<br>Yujie <br>
