 Scipy FFT functions syntax and method leodavinci1990 Programmer named Tim Posts: 10 Threads: 7 Joined: Feb 2019 Reputation: 0 Likes received: 0 #1 Mar-11-2019, 11:35 PM Hi, I am looking at the Fourier Transforms functions provided by the scipy library found at https://docs.scipy.org/doc/scipy/referen...tpack.html ```from scipy.fftpack import fft # Number of sample points N = 600 # sample spacing T = 1.0 / 800.0 x = np.linspace(0.0, N*T, N) y = np.sin(50.0 * 2.0*np.pi*x) + 0.5*np.sin(80.0 * 2.0*np.pi*x) yf = fft(y) xf = np.linspace(0.0, 1.0/(2.0*T), N//2) import matplotlib.pyplot as plt plt.plot(xf, 2.0/N * np.abs(yf[0:N//2])) plt.grid() plt.show()```Can someone please explain what is happening at line 9 and 11. And why is there a floor division in both lines? « Next Oldest | Next Newest »
