Python numpy.empty_like()用法及代碼示例

numpy.empty_like(a，dtype = None，order ='K'，subok = True)：返回形狀和類型與給定數組相同的新數組。
參數：

shape : Number of rows
order : C_contiguous or F_contiguous
dtype : [optional, float(by Default)] Data type of returned array.  
subok : [bool, optional] to make subclass of a or not

返回：

array with the same shape and type as a given array.

# Python Program illustrating 
# numpy.empty_like method 
  
import numpy as geek 
  
a = geek.empty_like([2, 2], dtype = int) 
print("\nMatrix a : \n", a) 
  
c = a = ([1,2,3], [4,5,6]) 
print("\nMatrix c : \n", geek.empty_like(c))

輸出：

Matrix a : 
 [  16843008 1058682594]

Matrix c : 
 [[0 0 0]
 [0 0 0]]
