Function intersectN2 finds all common pairs of input vectors aL1_ and aL2_
L1 : N1x2 or 2xN1 vector
L2 : N2x2 or 2xN2 vector
U is a N3x2 vector containing all common elements
n1 : index vector common elements L1(n1,:) in L1.
n2 : index vector common elements L2(n2,:) in L2.
the following conditions are staisfied: isequal(L1(n1,:),L2(n2,:))
If there are no common errors U n1 and n2 are null contents.
Input Output Restrictions: 1.- The input vectors have to be of dimensions N1x2 N2x2 or 2xN1 2xN2
2.- Strict number of input arguments, only 2, no more than 2 input vectors
3.- Strict amount of output arguments, only 3, no more than 3
