numpy.dual

This module is deprecated. Instead of importing functions from numpy.dual, the functions should be imported directly from NumPy or SciPy.

Aliases for functions which may be accelerated by SciPy.

SciPy can be built to use accelerated or otherwise improved libraries for FFTs, linear algebra, and special functions. This module allows developers to transparently support these accelerated functions when SciPy is available but still support users who have only installed NumPy.
