What is the recommended way to extend sage classes? - I want to add
some functionality to the complex matrix class - specifically tests
for: is_symmetric, is_hermitian, is_unitary etc... you get the idea.
I have experienced and read that this is not so straightforward.
I guess I could do it by
x_double_dense.pyx, which seems odd.

Can anyone cast any light on this for me?
This is OOB sage python

Thanks Michael - that's a very good heads up - I'll take some time to
digest the issues and get working on an approach that makes sense for
the widest community - we want a well supported capability with a
future.

I tried building sage 3.0.1 with David Philps patches - make failed
first with the r build looking for sage (which is in there somewhere
but without packages in place) so I did a make -k and have attached
the install.log - I've got a nice framework python and a half baked
sage and cvxopt build sti
I lied about attaching the log (I have a bzipped log if that's of any

On a more upbeat note: the only motivation for all this grief was to
build pycuda - against boost - against a framework based python. I
have not been so impressed with CUDA for basic matrix operations
relative to a fast muti-core CPU on relatively small matrices (though
I really like the pycuda a

A couple of trivial problems arose:
1. had to set MACOSX_DEPLOYMENT_TARGET=10.3 (why not 10.4?) as this

undefined dynamic_lookup. Workaround was to set this globally, may

Ok - got there in the end...
I did a fresh build (OS X 10.5.4 intel) with 3.1.1 sources.
Applied David's patches and fixed up the externs in cvxopt sources as
he indicated. All built just fine.
All test pass apart from trace - which is no doubt due to sage command
line not being able to load rea
I am happy to report that boost_1_35_0, pycuda 0.9 (plus my hacks) are
all now working and tested against this build. Thanks to David for his
help and patches. Game on.
