Dear Petsc team, I'm trying to implement PDE constrained optimization using TAO from the petsc4py interface. Since my problem has multiple parameter fields to optimize, I need to combine them into a single Vec object to supply to TAO. I've found the VecConcatenate in the C documentation, which appears to do exactly what I need, however this function does not seem to exist in the python interface (or at least I was unable to find it). Is there an other easy way to combine vectors from python?
Thanks for your help, Armand Touminet
