關於：
numpy.iscomplex(array)：逐一測試是否為複數(不是無窮大還是不是數字)，然後將結果作為布爾數組返回。
參數：
array:[array_like] Input array whose element we want to test
返回：
boolean array containing the result
代碼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")輸出：
Is Complex: [ True False] Is Complex: [ True False]
代碼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 begining
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))輸出：
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]]
