def ones ( shape , dtype = None , order = C )

Matrix of ones.

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

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'.

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