Error

Rstudio (FOSS) can do this but I don't remember what library.

I was introduced to Fourier analysis in a time series analysis class. Haven't had to use it yet but very interesting.

import numpy as np
from scipy import signal
import matplotlib.pyplot as plt
import pywavelets
import pandas

while many things can be done with scipy etc., and there is even a Python library for control (basic) engineering, there is no Python equivalent to Simulink and IMHO NumPy syntax for arrays is more clumsy when compared with matlab elegant syntax for matrices

Fair enough
