Python numpy.iscomplex()

Python numpy.iscomplex()函数按元素测试它是否是复数(不是无穷大或不是数字)，并将结果作为布尔数组返回。

语法 :

numpy.iscomplex(array)

参数 :

array : [array_like] 输入数组，我们要测试其元素。

返回 :

包含结果的布尔数组

示例 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")

输出 :

Is Complex :  [ True False] 

Is Complex :  [ True False] 

示例 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))

输出 :

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]]
