numpy.iscomplexobj(array) : This logical function helps to checks for the complex type of an array or array of a complex number. Even if imaginary part is equal to zero, it is considered to be an Complex Object.
Parameters :
array : [array_like]Input array or object whose elements, we need to test.
Return :
True, if the input array has a complex element; otherwise False
Code 1 :
# Python program explaining
# iscomplexobj() function
import numpy as np
in_array = [1, 3, 5, 4]
print ("Input array : ", in_array)
output_value = np.iscomplexobj(in_array)
print ("\nIs complex : ", output_value)
Output :
Input array : [1, 3, 5, 4] Is complex : False
Code 2 :
# Python Program illustrating
# numpy.iscomplexobj() method
import numpy as geek
# Returns True/False value for each element
a = geek.arange(20).reshape(5, 4)
print("Is complex : \n", geek.iscomplexobj(a))
# Returns True/False value as ans
# because we have mentioned dtpe in the beginning
b = geek.arange(20).reshape(5, 4).dtype = complex
print("\n",b)
print("\nIs complex : ", geek.iscomplexobj(b))
b = [[1j],
[3]]
print("\nIs complex : \n", geek.iscomplexobj(b))
Output :
Is complex : False class 'complex' Is complex : False Is complex : True
