Python | Numpy np.ifftn() method
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.
# 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 :
# 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]]
