%description
FFTW is a collection of fast C routines for computing the Discrete
Fourier Transform in one or more dimensions. It includes complex,
real, and parallel transforms, and can handle arbitrary array sizes
efficiently. This RPM package includes the double precision FFTW
uniprocessor and threads libraries.

%description -l pl.UTF-8
FFTW jest zbiorem szybkich funkcji C do obliczania dyskretnych
transformat Fouriera w jednym lub więcej wymiarach. Zawiera również
zespolone, rzeczywiste oraz równoległe transformaty i potrafi wydajnie
radzić sobie z tablicami o dowolnych rozmiarach. Ten pakiet RPM
zawiera wersje FFTW o podwójnej precyzji dla architektur
jednoprocesorowych oraz z obsługą wątków.

%description -l pt_BR.UTF-8
FFTW é uma coleção de rotinas rápidas em C para computar a Discrete
Fourier Transform em uma ou mais dimensões. Incluindo transformações
complexas, reais e paralelas, também pode manipular vetores de tamanho
arbitrário eficientemente. Esse pacote RPM inclui bibliotecas FFTW com
suporte a threads, normal e dupla precisão (Os arquivos de precisão
normal tem um prefixo "s").
