Python | Numpy np.fft() method

With the help of np.fft() method, we can get the 1-D Fourier Transform by using np.fft() method.

Syntax : np.fft(Array) Return : Return a series of fourier transformation.

Example #1 : In this example we can see that by using np.fft() method, we are able to get the series of fourier transformation by using this method. Output :

[25. + 0.j 1.11803399 + 1.08981379j -1.11803399 + 4.61652531j -1.11803399 - 4.61652531j 1.11803399 - 1.08981379j]

Example #2 :

Output :

[-12.1 + 0.j -3.85 - 5.68870985j -3.85 - 16.52766106j -3.85 + 16.52766106j -3.85 + 5.68870985j]
