<br>
thank you for providing such a marvellous numerics package, we had/have a lot of fun using it. For our purposes it was necessary to use Petsc with c++, float128 and complex. Since this is not possible with the standard build we made a patch. It uses c style complex numbers as a workaround.<br>
It can be used with the Parmetis package (there is a little fix in the interface there) and we have made a Slepc patch that then also allows to use c++, float128 and complex.<br>
It would be great if you could include it in the petsc software.<br>
We checked the patch for v3.7.6 and v3.7.3 (latest Slepc release)<br></blockquote><div><br></div><div>One question. Why would you compile PETSc with C++ if you wanted to use C99 complex?
