New in version 1.4.0. This module provides a number of objects (mostly functions) useful for dealing with Polynomial series

numpy.irr(values)

numpy.rollaxis(a, axis, start=0)

numpy.random.random_integers(low, high=None, size=None) Random integers of type np.int between low

numpy.fft.hfft(a, n=None, axis=-1, norm=None)

numpy.unwrap(p, discont=3.141592653589793, axis=-1)

numpy.polynomial.hermite.hermcompanion(c)

numpy.lookfor(what, module=None, import_modules=True, regenerate=False, output=None)
