well, std::valarray is not the same as std::vector, though there are similarities, so the example would be helpful. Of greatest concern to me is the memory management issue -- it would be nice to be able to share the data black between the valarray and the numpy array (rather than copying back and forth), but as the both valarrays and vectors are re-sizeable, that might get tricky. I'm assuming that you can get the pointer to the data block from both, but it might change on you. If you solve that for std::vector, the solution is likely to be similar for std:valarray. (I hope).

Of course, the better tested the better, but anything is probably better than starting from scratch!

Looked at both, and they are a great starting point, but only deal with plain old C arrays, as far as I've seen. Unless someone speaks up, it sounds like it's not been done, but there are at least a few of us that are interested, so maybe we can start a collaboration. -Chris By the way, David G. and I are working on the same project, so we're kind of like one person.... -- 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] _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
