numpoly.atleast_1d

numpoly.atleast_1d(*arys: numpoly.typing.PolyLike) → Union[numpoly.baseclass.ndpoly, List[numpoly.baseclass.ndpoly]]

Convert inputs to arrays with at least one dimension.

Scalar inputs are converted to 1-dimensional arrays, whilst higher-dimensional inputs are preserved.

Args:

arys:

One or more input arrays.

Return:

An array, or list of arrays, each with a.ndim >= 1. Copies are made only if necessary.

Example:

>>> numpoly.atleast_1d(numpoly.variable())
polynomial([q0])
>>> numpoly.atleast_1d(1, [2, 3])
[polynomial([1]), polynomial([2, 3])]
