Hi Boyd,
I doing similar things and have made a wrapper for a malloc-ed C
arrray. Your welcome to have the code, it's not a 'library' as such
but just a very simple class (http://www.boyfarrell.com/projects/
dynamicdouble/dynamicdouble.zip). I recently abandoned it after
proving the concept because I realised I needed something with
arbitrary precision (http://www.boyfarrell.com/projects/).
Contact me if you need any help with that.

I've created some rather simple classes to deal with arrays and

working strictly with NSNumber is cocoa and OOP overkill (at least
for my purposes), and as an old c-coder with lots of legacy code
that makes use of arrays of doubles, I find it a lot easier to
think in these terms. Thus far, I've not run into any problems
with my code, but it seems likely that I'm re-inventing the wheel.
Surely someone else using cocoa for scientific computing has
already created a nice family of classes that handle arrays and
matrices of ints and doubles. I know that this sort of stuff is
common in c++, but from what I've read on this list, I'd like to
avoid using both objective-c and c++ in the same project. If
someone knows of an objective-c library for doing this sort of
thing, I'd very much appreciate receiving information about it.
Thanks, Boyd
