# numpy.matrix.base#

attribute

- matrix.base#
Base object if memory is from some other object.

Examples

The base of an array that owns its memory is None:

>>> import numpy as np >>> x = np.array([1,2,3,4]) >>> x.base is None True

Slicing creates a view, whose memory is shared with x:

>>> y = x[2:] >>> y.base is x True
