Complex One-dimensional Transforms Tutorial. The basic usage of FFTW is simple. A typical call to FFTW looks like: #include <fftw.h> ... { fftw_complex in174827, out174827; fftw_plan p; ... p = fftw_create_plan(N, FFTW_FORWARD, FFTW_ESTIMATE); ... fftw_one(p, in, out); ... fftw_destroy_plan(p); }
Tutorial (FFTW 3.3.10)
http://www.fftw.org/fftw3_doc/Tutorial.html
We recommend that you read this tutorial in order. 1 At the least, read the first section (see Complex One-Dimensional DFTs) before reading any of the others, even if your main interest lies in one of the other transform types. Users of FFTW version 2 and earlier may also want to read Upgrading from FFTW version 2.

We start by describing the basic interface/features of FFTW in Chapter 2 [Tutorial], page 3. Next, Chapter 3 [Other Important Topics], page 15, dis-cusses data alignment (see Section 3.1 [SIMD alignment and fftwmalloc], page 15), the
A short tutorial on the basic usage of the package FFTW3
http://www2.math.uu.se/~figueras/Other/text/fftw_tutorial.pdf
This tutorial is designed as a short introduction to the basic usage of the library FFTW3. The purpose of it is to save some time to the reader while he is introduced to the basics of this library. By no means it is intended to substitute the great tutorial that can be found in [3], so we encourage to go through it in order to master it.

In terminal, type $ sudo port install fftw-3. This will install the FFTW library; make sure that you check the opt/local/include and opt/local/lib folders for the existence of the fftw3.h and libfftw3.a files respectively. You are done – you can now run ASPiK plugin projects that require FFTW.

Introduction. FFTWis a Csubroutine library for computing the discrete Fourier transform (DFT)in one or more dimensions, of arbitrary input size, and of both realand complex data (as well as of even/odd data, i.e. the discretecosine/sine transforms or DCT/DST). We believe that FFTW,which is free software, should become the FFTlibrary of choice for mostapplications.
