Hi guys. Following up on a previous user request, I've been looking at supporting hermitian mat-vec multiplication for the SBAIJ implementation. I haven't played with petsc before, so please forgive me for not understanding the internals. So, SBAIJ uses the transpose of the upper band where access to the lower band is needed. Am I right to believe that what is needed to be done is to have the SBAIJ data retriever (such as MatGetValues_MPISBAIJ) modified such that on sub-diagonal accesses the conjugate of the original values are returned instead (possibly by updating the contents of the "v" argument once filled in)?
Cheers, Christos
