No, Scientific Python is "a collection of Python modules that are useful for scientific computing" written by Konrad Hinsen. I'm not a user, but you can find information here: http://starship.python.net/~hinsen/ScientificPython/ SciPy is, I believe, a more recent and more ambitious project. In any event it is not directly related to ScientficPython. Information here: http://scipy.org/ Both of these packages are built on top of one of the three extant array extensions for Python. To try to clear up some of the confusion around those, let me summarize the states of these three packages as I understand it: Numeric: This is the origingal array package. Numarray: This was written as a replacement for Numeric. It has improved performance for large arrays. The internals were also simplified and many other improvements were made (arrays were subclassable, numeric signal handling vastly improved, etc). Unfortunately, a side effect of the changes was that small array performance got worse. There was a signifigant chunk of the numeric community for whom this was a deal breaker and as a result there ended up being a split between the Numeric and Numarray communities. Numpy: This is a rewrite of Numeric that incorporates most of the improvements in Numarray. It is designed to bring the two halves of the Python numeric community back together. So far, it seems to have gotten a positive reception. It is currently at 0.9.4 and I expect a stable 1.0 version in relatively short order. If I were starting with Python numerics, this is where I would start, although I've yet to start converting my Numarray based code over. I hope that sheds some light on this. regards, -tim > > "Brendan" <[EMAIL PROTECTED]> wrote in message > news:[EMAIL PROTECTED] > >>As of version 0.4.x, Scipy exclusively uses the newer NumPy module >>instead of the older Numeric module.
