numpy was written to replace both Numeric and numarray. There is a good
explanation in Chapter 1 of _The Guide to NumPy_ included in the sample chapters:

There were a number of features in Numeric that could not be replicated in
numarray, among them the ufunc C API and the speed for small arrays. numpy's
code base is closer to Numeric's but it incorporates nearly all (if not all) of
the features of numarray. The numarray developers fully support the migration to
numpy as the one array package.
