===========
![Rust](https://github.com/rust-math/fftw/workflows/Rust/badge.svg)

Rust bindings for the [FFTW C-library](http://www.fftw.org/) for computing discrete Fourier transforms, as well as discrete cosine and sine transforms.

This repository includes three crates:

  `fftw-src`: A crate for downloading and compiling the FFTW library


Feature flags
--------------

- `source`: Download and compile FFTW (default)
    - (Linux, macOS) Needs a C-compiler and the `make` build tool to compile the FFTW library
    - (Windows) Downloads a precompiled binary from the [FFTW website](http://www.fftw.org/install/windows.html)
- `system`: Use the system's libfftw3 (experimental)
    - You must install FFTW before building this crate
    - For Linux systems, please install FFTW using your package manager, e.g. in Debian or Ubuntu run `apt install libfftw3-dev`
    - For macOS, please run `brew install fftw` by using [homebrew](https://github.com/Homebrew/brew)
    - This feature is unsupported on Windows
- `intel-mkl` Use Intel MKL backend through [intel-mkl-src](https://github.com/termoshtt/rust-intel-mkl)
    - Only Linux and Windows are supported
