Python | Numpy np.ifftn() method Last Updated : 21 Nov, 2019 Comments Improve Suggest changes Like Article Like Report With the help of np.ifftn() method, we can get the N-D Inverse Fourier Transform by using np.fftn() method. Syntax : np.ifftn(Array) Return : Return a N-D series of inverse fourier transformation. Example #1 : In this example we can see that by using np.ifftn() method, we are able to get the N-D series of inverse fourier transformation by using this method. Python3 1=1 # import numpy import numpy as np a = np.array([-1, 3, -4, 7, 0]) # using np.ifftn() method gfg = np.fft.ifftn(a) print(gfg) Output : [ 1. +0.j -0.5-0.72249365j -0.5+2.44499549j -0.5-2.44499549j -0.5+0.72249365j] Example #2 : Python3 1=1 # import numpy import numpy as np a = np.array([[-5.5, 4.4, -6.6, 3.3, -7.7], [1.1, -3.3, 4.4, -7.7, 0]]) # using np.ifftn() method gfg = np.fft.ifftn(a) print(gfg) Output : [[-1.76+0.j -0.11+0.96624249j -0.11+0.30801859j -0.11-0.30801859j -0.11-0.96624249j] [-0.66+0.j -0.66+0.17149948j -0.66+2.99751362j -0.66-2.99751362j -0.66-0.17149948j]] Comment More infoAdvertise with us Next Article Python | Numpy np.ifftn() method J Jitender_1998 Follow Improve Article Tags : Python Python-numpy Python numpy-Matrix Function Practice Tags : python Similar Reads Python | Numpy np.ifft() method With the help of np.ifft() method, we can get the 1-D Inverse Fourier Transform by using np.ifft() method.
