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.

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