discretize.utils.Zero#

Inheritance diagram of Zero
class discretize.utils.Zero[source]#

Carries out arithmetic operations between 0 and arbitrary quantities.

This class was designed to manage basic arithmetic operations between 0 and numpy.ndarray of any shape. It is a short circuiting evaluation that will return the expected values.

Examples

>>> import numpy as np
>>> from discretize.utils import Zero
>>> Z = Zero()
>>> Z
Zero
>>> x = np.arange(5)
>>> x + Z
array([0, 1, 2, 3, 4])
>>> Z - x
array([ 0, -1, -2, -3, -4])
>>> Z * x
Zero
>>> Z @ x
Zero
>>> Z[0]
Zero
