dask.array.atleast_1d

dask.array.atleast_1d(*arys)[source]

Convert inputs to arrays with at least one dimension.

This docstring was copied from numpy.atleast_1d.

Some inconsistencies with the Dask version may exist.

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

Parameters
arys1, arys2, …array_like

One or more input arrays.

Returns
retndarray

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

Examples

>>> import numpy as np  
>>> np.atleast_1d(1.0)  
array([1.])
>>> x = np.arange(9.0).reshape(3,3)  
>>> np.atleast_1d(x)  
array([[0., 1., 2.],
       [3., 4., 5.],
       [6., 7., 8.]])
>>> np.atleast_1d(x) is x  
True
>>> np.atleast_1d(1, [3, 4])  
(array([1]), array([3, 4]))
