{wiki=FFTW}
FFTW, which stands for Fastest Fourier Transform in the West, is a widely used software library for computing Discrete Fourier Transforms (DFTs) and their variants. It is particularly notable for its efficiency and performance in executing large and multi-dimensional DFTs. Key features of FFTW include: 1. **Optimized Algorithms**: FFTW leverages advanced algorithms to compute DFTs efficiently, making it often faster than other libraries for many sizes of input data.
