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
# 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
# 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 beginningb = 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]]
