WebDec 29, 2013 · Here is an example. It does two things. First, it prepares an input array in[N] as a cosine wave, whose frequency is 3 and magnitude is 1.0, and Fourier transforms it. So, in the output, you should see a peak at out[3] and and another at out[N-3].Since the magnitude of the cosine wave is 1.0, you get N/2 at out[3] and out[N-3].. Second, it … WebFFTWの使い方を説明します。 DFT (discrete fourier transform) や DCT (discrete cosine transform) が計算できます。 download & make FFTWをdownload / makeします。 console mkdir fftw cd fftw/ wget http://www.fftw.org/fftw-3.3.8.tar.gz tar xzvf fftw-3.3.8.tar.gz cd fftw-3.3.8/ ./configure make sudo make install code example FFTWを使ってDCT IVを計 …
