Compute the Alpha-Interval of a Fuzzy Number
We have α-Int(A) := [int_0^1 α A_L(α) dα, int_0^1 α A_U(α) dα].

Note that if an instance of the FuzzyNumber
or
DiscontinuousFuzzyNumber
class
is given, the calculation is performed via numerical integration.
Otherwise, the computation is exact.
Returns numeric vector of length 2.
