Eliminating common elements across multiple arrays

i have data like-

A1  x    A2  y
1  1.2    1  1.3
3  1.3    2  1.6
4  1.4    3  1.5
5  1.5    4  1.4
8  1.4    6  1.4
9  1.7    7  1.7
11  1.6    8  1.5
12  1.3    9  1.7
14  1.6    10  1.2
15  1.8    12  1.3
      13  1.2
      14  1.5
      15  1.9

and i want the output in which both are common like-

A  x  y
1  1.2  1.3
3  1.3  1.5
4  1.4  1.4
8  1.4  1.5
9  1.7  1.7
12  1.3  1.3
14  1.6  1.5
15  1.8  1.9

This is easy using intersect and some basic MATLAB indexing:

Ax = [1;3;4;5;8;9;11;12;14;15]; 
x =  [1.2;1.3;1.4;1.5;1.4;1.7;1.6;1.3;1.6;1.8];
Ay = [;1;2;3;4;6;7;8;9;10;12;13;14;15];
y =  [1.3;1.6;1.5;1.4;1.4;1.7;1.5;1.7;1.2;1.3;1.2;1.5;1.9];
[A,idx,idy] = intersect(Ax,Ay);
xn = x(idx);
yn = y(idy);

which gives:

>> [A,xn,yn]
ans =
  1    1.2000    1.3000
  3    1.3000    1.5000
  4    1.4000    1.4000
  8    1.4000    1.5000
  9    1.7000    1.7000
 12    1.3000    1.3000
 14    1.6000    1.5000
 15    1.8000    1.9000
