sci The Fastest Fourier Transform in the West is a C subroutine library for computing the Discrete Fourier Transform (DFT) in one or more dimensions, of both real and complex data, and of arbitrary input size. It is becoming the FFT library of choice for most applications. Benchmarks, performed on a variety of platforms, show that FFTW's performance is typically superior to that of other publicly available FFT software. Adds support for Advanced Vector Extensions Link default library to single precision instead of double (symlinks only and fftw-2.1) Use the Fused Multiply Add instruction set (fma3/fma4 either one) Build quadruple precision lib Adds support for ZBus cycle-counter of mips fftw
