Create an interval enclosure for a list of parameters.
Parameters can be simple numbers, intervals or interval literals as strings. If needed, broadcasting is performed.
NaNs represent missing values and are treated like empty intervals. Inf and
-Inf can be used to create unbound intervals, but note that these values
will not be members of the interval. In particular, it is not possible to
create an interval with hull (inf).
The result is equivalent to
union (infsupdec (X1), union (infsupdec (X2), …)), but
computed in a more efficient way. In contrast to the union function, this
function is not considered a set operation and the result carries the best
possible decoration, which is allowed by the input parameters.
Warning: This function is not defined by IEEE Std 1788-2015 and shall not be
confused with the standard’s convexHull function, which is implemented by
union.
Accuracy: The result is a tight enclosure.
hull (1, 4, 3, 2)
⇒ ans = [1, 4]_com
hull (empty, entire)
⇒ ans = [Entire]_trv
hull ("0.1", "pi", "e")
⇒ ans ⊂ [0.099999, 3.1416]_com
hull ("[0, 3]", "[4, 7]")
⇒ ans = [0, 7]_com
