numpy.matlib.zeros()函数| Python

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

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