numpy.empty_like(a,dtype = None,order ='K',subok = True):返回形状和类型与给定数组相同的新数组。
参数:
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))
输出:
Matrix a : [ 16843008 1058682594] Matrix c : [[0 0 0] [0 0 0]]
