Python numpy.broadcast_to()函数

numpy.broadcast_to()函数将一个数组广播到一个新的形状。

语法: numpy.broadcast_to(array, shape, subok = False)

参数 :

array : [array_liket] 要广播的阵列。

shape : [tuple] 所需数组的形状。

subok : [bool, optional] 如果为真，则子类将被通过，否则默认情况下，返回的数组将被强制为基类数组。

返回： [array] 输出数组。

代码 #1 :

# Python program explaining
# numpy.broadcast_to() function
   
# importing numpy as geek
import numpy as geek
   
arr = geek.array([1, 2, 3, 4])
  
gfg = geek.broadcast_to(arr, (4, 4))
   
print(gfg)

输出 :

[[1 2 3 4]

[1 2 3 4]

[1 2 3 4]

[1 2 3 4]]

代码#2 :

# Python program explaining
# numpy.broadcast_to() function
   
# importing numpy as geek
import numpy as geek
   
arr = geek.array([1, 2, 3, 4, 5])
  
gfg = geek.broadcast_to(arr, (5, 5))
   
print(gfg)

输出 :

[[1 2 3 4 5]

[1 2 3 4 5]

[1 2 3 4 5]
