One or more input arrays.

Returns

Views inputs as arrays with at least two dimensions.

atleast_3d

Examples

>>> import nlcpy as vp
>>> vp.atleast_1d(1.0)
array([1.])

>>> x = vp.arange(9.0).reshape(3,3)
>>> vp.atleast_1d(x)
array([[0., 1., 2.],
       [3., 4., 5.],
       [6., 7., 8.]])
>>> vp.atleast_1d(x) is x
True

>>> vp.atleast_1d(1, [3, 4])
[array([1]), array([3, 4])]
