Absolutely. Though now that you mention it, isn't there one in boost::python? or at least one that worked with Numeric. > projects all had home-grown, semi-complete solutions. > A standard wrapper would be good for all of the reasons you mention > (basically resource management), but also to have a cleaner syntax for > accessing the elements that would abstract away striding, ordering etc. I think I'm thinking of something slightly different. What I'd like is set of array classes that can interface well with numpy, and also be quite usable all by themselves in C++ code that has nothing to do with python. I don't really envision a C++ ndarray -- I generally think of C++ as static enough that I'm happy to define that I need, for example, a NX2 array of doubles. I don't see using a generic array like ndarray that could hold any type, shape, etc. But maybe others do -- it would be pretty cool. I guess to some extent the question is whether you are writing extensions for python, or a C++ that you want to use from C++, and also wrap for python. But maybe both need can be met by the same C++ classes (templates?) > It may actually be possible to build it around boost::multiarray Do you know off hand if multiarray can be constructed from an existing pointer to a data block? > Can't imagine I'll find time for it anytime soon, too bad, but if you do -- I'd love to hear about it! -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Matplotlib-devel mailing list Matplotlib-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-devel
