- numpy.atleast_2d(*arys)[source]#
View inputs as arrays with at least two dimensions.
- Parameters
- arys1, arys2, …array_like
One or more array-like sequences. Non-array inputs are converted to arrays. Arrays that already have two or more dimensions are preserved.
- Returns
- res, res2, …ndarray
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.
