Hello -- I'm a Numpy Newbie. I have a question for the Numpy gurus about
comparisons of multiarray objects and arrays of booleans in particular.
Back when I was checking out Numpy for an application, I read a note in the
Ascher/Dubois/Hinsen/Hugunin/Oliphant manual about comparisons of multiarray
objects. It said and still says:
"Currently, comparisons of multiarray objects results in exceptions,
since reasonable results (arrays of booleans) are not doable without
non-trivial changes to the Python core. These changes are planned for
Python 1.6, at which point array object comparisons will be updated."
( http://numpy.sourceforge.net/numdoc/HTML/numdoc.html )
Can anyone comment on what's happening with arrays of booleans in Numpy?
I don't want to duplicate someone elses effort, but don't mind standing
on someone elses shoulders. My application calls for operations on both
non-sparse and sparce matrices.
