.SH DESCRIPTION
|
|
17 |
The
|
|
18 |
.I libfftw
|
|
19 |
3.1.2 library is a C subroutine library for computing the discrete Fourier
|
|
20 |
transform (DFT) in one or more dimensions, of arbitrary input size,
|
|
21 |
and of both real and complex data (as well as of even/odd data, i.e.
|
|
22 |
the discrete cosine/sine transforms or DCT/DST).
|
|
23 |
|
|
24 |
Benchmarks, performed on on a variety of platforms, show that FFTW's
|
|
25 |
performance is typically superior to that of other publicly available
|
|
26 |
FFT software, and is even competitive with vendor-tuned codes. In
|
|
27 |
contrast to vendor-tuned codes, however, FFTW's performance is
|
|
28 |
portable: the same program will perform well on most architectures
|
|
29 |
without modification. Hence the name, "FFTW," which stands for the
|
|
30 |
somewhat whimsical title of "Fastest Fourier Transform in the West."
