This package wraps Numpy's fft module to produce unitary transforms
and power spectra of real numbers in one dimension.  See the code for
the technical details.


== Installation ==

Non-Python dependencies (Debian packagename):
  easy_install  (python-setuptools)
  Numpy source  (python-numpy-dev)

FFT_tools uses `setuptools' for installation.  Setuptools is basically
an extension of the standard Python distutils package which supports
automatic package dependency tracking.  The installation procedure
should be (on Debian-esque systems)
  # apt-get intall python-setuptools python-numpy-dev
  # easy_install -f http://www.physics.drexel.edu/~wking/code/python/ FFT_tools

There is one speedbump you might run into:
  * an outdated version of easy_install (see ez_setup.py section)

** ez_setup.py

This package bundles
  http://peak.telecommunity.com/dist/ez_setup.py
to bootstrap setuputils installation on your machine (if neccessary).

If the bootstrapping doesn't work, you may need to install a current version
of setuptools.  On Debian-based systems `apt-get install python-setuptools'.
Once you have *some* version of setuptools, upgrade with
  easy_install -U setuptools
