discretize.utils.Zero

class discretize.utils.Zero

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.

Attributes

T	Return the Zero class as an operator.
ndim	Return the dimension of Zero class, i.e. None.
shape	Return the shape Zero class, i.e. None.

Methods

transpose()

Return the transpose of the Zero class, i.e. itself.

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
