Hi,
I would like to use DMGetLocalVector and DMGetGlobalVector with
petsc4py but I didn't find the appropriate methods. If they are not
implemented, I can do a PR with these functions and their Restore part.
You are right, these are missing.
OK I will add these functions and do a PR.
I have an other problem: I have to optimize a Python function that
take a numpy array given by the function getVecArray of a DMDA and I
would like to use Pythran to do that. The problem is that Pythran
doesn't recognize the array as a numpy array because the flags
C_CONTIGUOUS and F_CONTIGUOUS are both set to False. Is there a
reason that the C_CONTIGUOUS flag is set to False and not to True ?
For this, can't you just use vec.getArray()?
It's ok if I use vec.getArray().
Thanks,
Loic
Thanks,
