What is Kiss FFT?

Kiss FFT is a small and simple FFT library. It has no complicated platform-specific optimizations, can do either fixed or floating point with just a recompile, and is efficient enough for all but the most demanding applications.

Is FFTW thread safe?

FFTW can be used in such an environment, but some care must be taken because the planner routines share data (e.g. wisdom and trigonometric tables) between calls and plans. The upshot is that the only thread-safe routine in FFTW is fftw_execute (and the new-array variants thereof).

Who invented the fast Fourier transform?

Cooley and Tukey
The fast Fourier transform (FFT) algorithm was developed by Cooley and Tukey in 1965. It could reduce the computational complexity of discrete Fourier transform significantly from \(O(N^2)\) to \(O(N\log _2 {N})\).

Where do I find the FFTW test files?

FFTW includes test programs, fftw_testand rfftw_test, in the testsdirectory. These are compiled and linked like any program using FFTW, except that they use additional header files located in the fftwand rfftwdirectories, so you will need to set your compiler #includepaths appropriately.

How to install FFTW on a UNIX System?

Installation on Unix FFTW comes with a configureprogram in the GNU style. Installation can be as simple as: ./configure make make install This will build the uniprocessor complex and real transform libraries along with the test programs. We strongly recommend that you use GNU makeif it is available; on some systems it is called gmake.

How to compile single precision version of FFTW?

To compile a single-precision version of the libraries: Add –enable-sse if your computers have i686 or x86-64 processors. By default, FFTW header files will be installed in /usr/local/include the library files in /usr/local/lib.

How to install FFTW with Windows F77 mangling?

–with-windows-f77-mangling: this will include Fortran wrappers for some common Windows Fortran compilers (GNU, Intel, and Digital). –enable-shared –disable-static: this will create DLLs instead of static libraries (since MinGW’s static-library format seems to be different from Microsoft’s).
