This book only briefly outlines some of the infrastructure that
surrounds the basic objects in NumPy to provide the additional
functionality contained in the older Numeric package (i.e.
LinearAlgebra, RandomArray, FFT). This infrastructure in NumPy
includes basic linear algebra routines, Fourier transform capabilities,
and random number generators. In addition, the f2py module is described
in its own documentation, and so is only briefly mentioned in the second
part of the book. There are also extensions to the standard Python
distutils and testing frameworks included with NumPy that are useful in
constructing your own packages built on top of NumPy. The central
purpose of this book, however, is to describe and document the basic
NumPy system that is available under the numpy namespace.
