what happened to information about setting -display DISPLAY etc and getting it
to work under various senerios? I cannot find it in faq.html is it somewhere
else or did it get lost over the years?
Thanks
Barry
the common cases a while back so it should
automatically work in most common configurations (no need to always -display
:0 to sign in).

Hallo,
May be this topic has already been discussed, I've not done search, but
anyway it seems that PetscBinaryRead from 3.1-p7 doesn't support reading
complex double dense matrices.
I had to add this code:
if (nz == -1)
if strcmp(comp,'complex')
s =
Thank you for letting us know. This is now fixed in petsc-dev

Hi,
I'm was sorting an array which that has duplicate entries: (x = [39 9 19 39
29]). I noticed that for duplicate entries after sorting, the index returned
are not in ascending. The example below will explain this further.
Here is the code snippet:

Here is the code snippet:
PetscSortIntWithPermutation() implements bubble sort for n8 and
insertion sort otherwise,
which does not give ordered index for duplicate entries. If you can
find the algorithm used by Matlab, please
let us know. We can implement it. Otherwise, I think you may write a
subroutine to sort

I suppose you can avoid both these gotchas by involving the end user in the
choice rather than making it arbitrarily. For example, in reconfigure:

As a related matter, could we add a field PETSC_PYTHON to petscvariables so
that Makefile users can run a consistent version?

I am making a change to PETSc that will break everything. XXXDestroy(XXX) is
replaced with XXXDestroy(XXX*) and in addition XXXDestroy(x) returns
immediately without error if x is null.
Won't be pushing until I've finished it all, it may take a few days.
