Class FuzzyVariable

Encapsulation of a fuzzy super set.

Method Summary
	`__init__(self, name, minValue, maxValue, unit)`
	`__getitem__(self, item)` Returns subset with name matching item.
	`addSubSet(self, setName, fitVector)` Adds new subset.
	`defuzzify(self)` Returns infered result of fuzzy evaluation.
	`getSegunoConstantForSubSet(self, setName)` Returns the Seguno constant for a specific set.
	`reset(self)` Sets set memenrs DOM to 0.0.
	`segunoValueIs(self, index, threshold)` Returns result of `valueIs` operation as the Seguno value.
	`setInputValue(self, inputValue)` Sets new input value for variable, and sets all member sets DOM to 0.0.
	`valueInSet(self, index, setName)` Returns the membership value in a specific set.
	`valueIs(self, index, threshold)` Returns list of sets in which the tested value has a member value greater then the threshold.
	`valuesFor(self, index)` Returns list of membership values for each of the subsets within this set.

Method Details

getitem(self, item)
(Indexing operator)

Returns subset with name matching item.

Parameters:: item - name for set
(type=string)

addSubSet(self, setName, fitVector)

Adds new subset.

Parameters:: setName - name for set
(type=string); fitVector - profile of values for set
(type=list)

defuzzify(self)

Returns infered result of fuzzy evaluation.

getSegunoConstantForSubSet(self, setName)

Returns the Seguno constant for a specific set.

Parameters:: setName - name of set to inspect
(type=string)

reset(self)

Sets set memenrs DOM to 0.0.

segunoValueIs(self, index, threshold=0.0)

Returns result of valueIs operation as the Seguno value.

Parameters:: index - value to test in sets
(type=float or integer); threshold - threshold for inclusion
(type=float)

setInputValue(self, inputValue)

Sets new input value for variable, and sets all member sets DOM to 0.0.

valueInSet(self, index, setName)

Returns the membership value in a specific set.

Parameters:: index - value to test in sets
(type=float or integer); setName - name of set to inspect
(type=string)

valueIs(self, index, threshold=0.0)

Returns list of sets in which the tested value has a member value greater then the threshold.

Parameters:: index - value to test in sets
(type=float or integer); threshold - threshold for inclusion
(type=float)

valuesFor(self, index)
