FIVEVagDist

FIVEVagDist:  Calculate the scaled distance of two points in the vague environment

                            [D]=FIVEVagDist(U,VE,P1,P2)

          Where:
          U: is the universe (a vector of discrete values in increasing order),
          VE: is the generated vague environment (the scaled distances on the universe U)
             If VE(k,1)=0, it is the primitive integral of the scaling function according
               to the elements of U
             If VE(k,1)=-1, it is the integral of the scaling function between
               the neighboring elements of U
          P1,P2 is two points (values), inside U
               If P1=NaN, or P2=NaN, then the vague distance is null (D=0)
          D: is the scaled distance of the two points P1,P2.
               D<0 denotes that D=inf. This case abs(D) is the number of inf
               values in VE between P1 and P2
          In case of U,VE,P,D the rows are the dimensions
