<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE pkgmetadata SYSTEM "http://www.gentoo.org/dtd/metadata.dtd"> <pkgmetadata> <herd>sci</herd> <longdescription lang="en"> 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. </longdescription> <use> <flag name="float">Link default library to single precision instead of double (symlinks only and fftw-2.1)</flag> <flag name="quad">Build quadruple precision lib</flag> <flag name="zbus">Adds support for ZBus cycle-counter of mips</flag> </use> <upstream> <remote-id type="freecode">fftw</remote-id> </upstream> </pkgmetadata>
