numpoly.atleast_2d#

numpoly.atleast_2d(*arys: numpoly.typing.PolyLike) → ndpoly | List[ndpoly][source]#

View inputs as arrays with at least two dimensions.

Args:

arys:: One or more array-like sequences. Non-array inputs are converted to arrays. Arrays that already have two or more dimensions are preserved.

Return:

An array, or list of arrays, each with a.ndim >= 2. Copies are avoided where possible, and views with two or more dimensions are returned.

Example:

>>> numpoly.atleast_2d(numpoly.variable())
polynomial([[q0]])
>>> numpoly.atleast_2d(1, [2], [[3]])
[polynomial([[1]]), polynomial([[2]]), polynomial([[3]])]
