Last Updated :

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
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
import numpy as geek
a = geek.arange( 20 ).reshape( 5 , 4 )
print ( "Is complex : \n" , geek.iscomplex(a))
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]]
