numpy.matlib.ones

matlib.ones(shape, dtype=None, order='C') [source]

Matrix of ones.

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

Parameters

shape{sequence of ints, int}

Shape of the matrix

dtypedata-type, optional

The desired data-type for the matrix, default is np.float64.

order{‘C’, ‘F’}, optional

Whether to store matrix in C- or Fortran-contiguous order, default is ‘C’.

Returns

outmatrix

Matrix of ones of given shape, dtype, and order.

See also

ones

Array of ones.

matlib.zeros

Zero matrix.

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

>>> np.matlib.ones((2,3))
matrix([[1.,  1.,  1.],
        [1.,  1.,  1.]])

>>> np.matlib.ones(2)
matrix([[1.,  1.]])
