NumPy is the fundamental general-purpose array_processing package for
scientific computing with
Pythondesigned to
efficiently manipulate large multi-dimensional arrays of arbitrary records without sacrificing too much speed for small multi-dimensional arrays.
NumPy is built on the Numeric code base and adds features introduced by numarray
