numpy.matlib.zeros

numpy.matlib.zeros(shape, dtype=None, order='C')[源代码]

Return a matrix of given shape and type, filled with zeros.

Parameters:
shape : int or sequence of ints

Shape of the 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’.

Returns:
out : matrix

Zero matrix of given shape, dtype, and order.

numpy.zeros
Equivalent array function.
matlib.ones
Return a matrix of ones.

Notes

If shape has length one i.e. (N,), or is a scalar N, out becomes a single row matrix of shape (1,N).

Examples

>>> import numpy.matlib
>>> np.matlib.zeros((2, 3))
matrix([[ 0.,  0.,  0.],
        [ 0.,  0.,  0.]])
>>> np.matlib.zeros(2)
matrix([[ 0.,  0.]])
