NumPy

NumPy is a mathematical library for Python that provides an array object, linear algebra functions, and Fourier transforms. It is a very popular way to do scientific computing in Python and it’s gaining popularity, in some cases replacing more purpose-built tools like MATLAB. NumPy is used in Chapter 10 to implement the NMF algorithm. The home page for NumPy is http://numpy.scipy.org.

Installation on Windows

There is a Windows binary installer available for NumPy at http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103.

Download the .exe file that matches your version of Python and run it. It will ask you for the directory where Python is installed and will install itself there.
