Discrete Fourier Transform with xarray

Project description

pypi package conda forge conda-forge GitHub Workflow CI Status code coverage documentation status DOI license Code style

xrft is an open-source Python package for taking the discrete Fourier transform (DFT) on xarray and dask arrays.

It is:

  • Powerful: It keeps the metadata and coordinates of the original xarray dataset and provides a clean work flow of DFT.

  • Easy-to-use: It uses the native arguments of numpy FFT and provides a simple, high-level API.

  • Fast: It uses the dask API of FFT and map_blocks to allow parallelization of DFT.

Please cite the doi if you find this package useful in order to support its continuous development.
