The numpy.iscomplex() function tests element-wise whether it is a complex number or not(not infinity or not Not a Number) and returns the result as a boolean array. Syntax :
numpy.iscomplex(array)
Parameters :
array : [array_like] Input array whose element we want to test
Return :
boolean array containing the result
Code 1 :
# Python Program illustrating
# numpy.iscomplex() method
import numpy as geek
print("Is Complex : ", geek.iscomplex([1+1j, 1+0j]), "\n")
print("Is Complex : ", geek.iscomplex([0+1j, 0]), "\n")
Output :
Is Complex : [ True False] Is Complex : [ True False]
Code 2 :
# Python Program illustrating
# numpy.iscomplex() method
import numpy as geek
# Returns True/False value for each element
a = geek.arange(20).reshape(5, 4)
print("Is complex : \n", geek.iscomplex(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.iscomplex(b))
b = [[1j],
[3]]
print("\nIs complex : \n", geek.iscomplex(b))
Output :
Is complex : [[False False False False] [False False False False] [False False False False] [False False False False] [False False False False]] Is complex : False Is complex : [[ True] [False]]
