Why the hell did 'python' move?

I agree with Barry here. When I first started playing with petsc, I found the "python" directory confusing and frustrating for quite some time. I think it was just because of the name! Simon. On Mon, 10 Dec 2007 10:16:13 -0600 Barry Smith wrote: > > I sent email about a week ago and no on

PETSc for Python

gramming (with all these different matrix types). That really excites me, but i guess it's beside the point right now. I'm cc'ing the petsc-dev list, hope thats OK. ciao! Simon. -- Simon Burton, B.Sc. Licensed PO Box 8066 ANU Canberra 2601 Australia Ph. 61 02 6249 6940 http://arrowtheory.com

patch for seqdense

so, do you have testing code for it? I can test it > once I see the MatMatMult_seqdense. We tested it using python. I see also there is a test in src/mat/examples/tests/ex94.c .

patch for seqdense

Hi, I sent through a patch to implement MatMatMult* for seqdense matrices. Here it is again; is there anything wrong with it ? It just calls through to BLASgemm_ . thanks, Simon. -- Simon Burton, B.Sc. Licensed PO Box 8066 ANU Canberra 2601 Australia Ph. 61 02 6249 6940 http

Is there a way to simulate a MatSet (like VecSet) ? Simon. -- Simon Burton, B.Sc. Licensed PO Box 8066 ANU Canberra 2601 Australia Ph. 61 02 6249 6940 http://arrowtheory.com

ufuncs, iterators

numarray do the work, but this seems doomed to failure because numarray is inherently dense. Simon. [1]: http://stsdas.stsci.edu/numarray/numarray-1.3.html/node35.html -- Simon Burton, B.Sc. Licensed PO Box 8066 ANU Canberra 2601 Australia Ph. 61 02 6249 6940 http://arrowtheory.com
