Python numpy.matlib.zeros()用法及代码示例

numpy.matlib.zeros()函数返回给定形状和类型的矩阵，并用零填充。

用法： numpy.matlib.zeros(shape, dtype = None, order = ‘C’)

参数：

shape  :[sequence of ints] Shape of the empty matrix.

dtype  :[data-type, optional] The desired data-type for the matrix, default is float.

order  :[{‘C’, ‘F’}, optional] Whether to store the result in C- or Fortran-contiguous order, default is ‘C’.

Return :[matrix] Zero matrix of given shape, dtype, and order.

# Python program explaining 
# numpy.matlib.zeros() function 
  
# importing numpy as geek  
# and importing matlib module   
import numpy as geek 
import numpy.matlib 
  
gfg = geek.matlib.zeros((3, 3)) 
  
print (gfg)

输出：

[[ 0.  0.  0.]
 [ 0.  0.  0.]
 [ 0.  0.  0.]]
