Background: Numeric is an add-on Python module that has seen widespread adoption. It enables Python to be used as a Scientific Computing Environment similar to MATLAB or IDL. Numeric was originally written nearly 10 years ago, and while still performing admirably, needed much updating to take advantage of the new features in Python and to remove old warts. SciPy Core 0.4.1 (beta) SciPy Core is a new system which builds on the code-base of Numeric, but implements features (such as advanced index-selection, and user-settable error modes). There are over 25 major new feature enhancements. The LICENSE is still a BSD style License---the same as old Numeric. More information can be found at the web-site: http://numeric.scipy.org The primary developer of scipy core (besides the original creators of Numeric upon which it is based) is Travis Oliphant (oliphant@ee.byu.edu), but his work received ideas and support from a wide cast of community members including: Pearu Peterson, Robert Kern, Perry Greenfield, Eric Jones, John Hunter, Fernando Perez, Konrad Hinsen, and Paul Dubois. These individuals should not be held responsible for any bugs remaining in the code. <P><A HREF="http://numeric.scipy.org">SciPy Core 0.4.1 (beta)</A> - Replacement for Numeric Python. (30-Sep-05)
