numpy.matlib.ones — NumPy v1.15 Manual (original) (raw)
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.]])
