jax.numpy.ones_like

jax.numpy.ones_like(a, dtype=None, shape=None)

Return an array of ones with the same shape and type as a given array.

LAX-backend implementation of ones_like(). Original docstring below.

Parameters

• a (array_like) – The shape and data-type of a define these same attributes of the returned array.

• dtype (data-type, optional) – Overrides the data type of the result.

• shape (int or sequence of ints, optional.) – Overrides the shape of the result. If order=’K’ and the number of dimensions is unchanged, will try to keep order, otherwise, order=’C’ is implied.

Returns

out – Array of ones with the same shape and type as a.

Return type

Examples

>>> x = np.arange(6)
>>> x = x.reshape((2, 3))
>>> x
array([[0, 1, 2],
       [3, 4, 5]])
>>> np.ones_like(x)
array([[1, 1, 1],
       [1, 1, 1]])

>>> y = np.arange(3, dtype=float)
>>> y
array([0., 1., 2.])
>>> np.ones_like(y)
array([1.,  1.,  1.])
