numpy.atleast_2d — NumPy v2.2 Manual (original) (raw)
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 tuple of arrays, each with a.ndim >= 2
. Copies are avoided where possible, and views with two or more dimensions are returned.
Examples
import numpy as np np.atleast_2d(3.0) array([[3.]])
x = np.arange(3.0) np.atleast_2d(x) array([[0., 1., 2.]]) np.atleast_2d(x).base is x True
np.atleast_2d(1, [1, 2], [[1, 2]]) (array([[1]]), array([[1, 2]]), array([[1, 2]]))
