numpy.matlib.ones

numpy.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 dtype : data-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:	out : matrix Matrix of ones of given shape, dtype, and order.

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.]])
