The procedure ALIAS_Volume allows to compute the volume of a box. It has 2 syntax:
double ALIAS_Volume(int Dim,INTERVAL_VECTOR &Box) double ALIAS_Volume(int Dim,int box,INTERVAL_MATRIX &BOX)The first syntax allows to compute the volume of the interval vector Box of size Dim, while the second syntax allows to compute the volume of the box defined by the box-th row of the interval matrix BOX: the row is supposed to have Dim elements.
