FFT-tools 0.4

Wrap NumpPy's FFT routines to reduce clutter.

FFT_tools: unitary FFTs and power spectra for real data.

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

Packages

Gentoo

I’ve packaged FFT-tools for Gentoo. You need layman and my wtk overlay. Install with:

# emerge -av app-portage/layman
# layman --add wtk
# emerge -av dev-python/FFT-tools

Dependencies

If you’re installing by hand or packaging pycomedi for another distribution, you’ll need the following dependencies:

Package	Debian	Gentoo
NumPy	python-numpy	dev-python/numpy

Installing by hand

FFT-tools is available as a Git repository:

$ git clone git://tremily.us/FFT-tools.git

See the homepage for details. To install the checkout, run the standard:

$ python setup.py install

Usage

See the tests in FFT_tools.py for simple examples.

Testing

Run internal unit tests with:

$ python -m FFT_tools

If you want to plot the test results (useful for debugging), you’ll need to install matplotlib. Then run:

$ python -m FFT_tools --plot
