|---|
| 9 | FFTW is a C subroutine library for computing the Discrete Fourier \ |
|---|
| 10 | Transform (DFT) in one or more dimensions, of both real and complex \ |
|---|
| 11 | data, and of arbitrary input size. We believe that FFTW, which is \ |
|---|
| 12 | free software, should become the FFT library of choice for most \ |
|---|
| 13 | applications. Our benchmarks, performed on a variety of platforms, \ |
|---|
| 14 | show that FFTW's performance is typically superior to that of other \ |
|---|
| 15 | publicly available FFT software. Moreover, FFTW's performance is \ |
|---|
| 16 | portable: the program will perform well on most architectures \ |
|---|
| 17 | without modification. |
