Find intersectional points of two discrete functions?

I have two line graphs (Y=Y(X) and Z=Z(X)) with n discrete points of three arrays: X=[X1 X2 ... Xn], Y=[Y1 Y2 ... Yn] and Z=[Z1 Z2 ... Zn]
I plot two graphs by command: plot(X, Y, X, Z);
Now I want to get all of intersectional points of these two graphs. What command in Matlab can I use to do this? Please help me. Thanks.

The description is not clear yet. Please add an example by editing the question (not by posting a pseudo-answer or by hiding information in a comment):
What is the desired output for X=1:3, Y=[0, 3, 2], Z=[1,2,2]?

C = intersect(A,B)
returns the values common to both A and B. The values of C are in sorted order.
