GetLabelMembership() public method

Calculate the membership of a given value to a given label. Used to evaluate linguistics clauses like "X IS A", where X is a value and A is a linguistic label.
The label indicated in labelName was not found in the linguistic variable.
public GetLabelMembership ( string labelName, float value ) : float
labelName string Label (fuzzy set) to evaluate value's membership.
value float Value which label's membership will to be calculated.
return float
