numpy.cbrt () in Python

Michael Zippo 18.07.2021

Parameters :

  arr:   [array_like]  Input array or object whose elements, we need to square.

Return:

 An array with cube root of x for all x ie array elements

Code # 1: Work

# Python program explaining
# cbrt () function

import numpy as np

arr1 = [ 1 , 27000 , 64 , - 1000 ]

print ( " cbrt Value of arr1: " , np.cbrt (arr1))

arr2 = [ 1024 , - 128 ]

print ( "cbrt Value of arr2:" , np.cbrt (arr2))

Output:

 cbrt Value of arr1: [1.30.4. - 10.] cbrt Value of arr2: [10.0793684 -5.0396842]

Code # 2: Working with Complex Numbers

       # Python program explaining  
  # cbrt () function  
   
   import   numpy as np  
   
   a   =   4   +   3j  
   print   (  "cbrt (4 + 3j):"  , np.cbrt (a)) 
   
   b   =   16   +   13j  
   print   (  "cbrt value (16 + 13j):"  , np.cbrt (b))

Output:

  TypeError:  ufunc ’cbrt’ not supported for the i nput types, and the inputs could not be safely coerced to any supported types according to the casting rule ’’ safe ’’

Code # 3: Graphical Representation

# Python program explaining
# cbrt () function

import numpy as np

import matplotlib.pyplot as plt

a = np.linspace ( start = - 5 , stop = 150 ,

num = 10 , endpoint = True )

print ( "Graphical Representation:" , np.cbrt (a))

plt.title ( "blue: with cbrt red: without cbrt" )

plt.plot (a, np. cbrt (a))

plt.scatter (a, a, color = ’red’ )

plt.show ()

< / code>

Output:

 Graphical Representation: [-1.70997595 2.30347441 3.08793243 3.60027433 3.99768384 4.3287262 4.61565763 4.87076238 5.10162421 5.31329285]
