) -> None

Constructor.

Parameters:

Name	Type	Description	Default
name	str	name of the variable	''
description	str	description of the variable	''
enabled	bool	enable the variable	True
minimum	float	minimum value of the variable	-inf
maximum	float	maximum value of the variable	inf
lock_range	bool	lock the value to the range of the variable	False
terms	Iterable[Term] | None	list of terms.	None

__str__

__str__() -> str

Return the code to construct the input variable in the FuzzyLite Language.

Returns:

Type	Description
str	code to construct the input variable in the FuzzyLite Language.

fuzzy_value

fuzzy_value() -> Array[str_]

Return the current fuzzy input value.

The fuzzy value is computed by evaluating the membership function of the current input value \(x\) for each term \(i\), resulting in a fuzzy input value in the form \(\tilde{x}=\sum_i{\mu_i(x)/i}\).

Returns:

Type	Description
Array[str_]	current fuzzy value expressed as \(\sum_i{\mu_i(x)/i}\).
