ToolPythonIntermediate Filtering with scipy.signal: mains hum and noise out of an ECG k50 = np.argmin(np.abs(freq - 50))print(f"harmonic {n:2d} {A_raw[np.argmin(np.abs(freq - f_n))]:.4f} mV at {f_n:.1f} Hz")k = np.argmin(np.abs(w - 103)) # label each line just above it at 103 Hz
ToolPythonBeginner Minimization with scipy.optimize.minimize: the shape of a seven-atom cluster best = results[np.argmin(energies)]
