Hi, I am very new to matlab and i was hopping someone could assist me with this simple problem I have two plotted lines FAR and FRR. FAR and FRR are two column vectors. I simply need to find the point of intersection, i just need the value where the intersection happens. Could someone please assist. My code is as follows
FRR FAR
1 0
0.984375 0.005331753555
0.953125 0.06575829384
0.8828125 0.1279620853
0.828125 0.1800947867
0.78125 0.2458530806
0.703125 0.3382701422
0.46875 0.4502369668
0.265625 0.5805687204
0.0859375 0.7357819905
plot(FAR);
hold;
plot(FRR);

I have edited the answer check it. You need to download the function interX and save it in your working folder.
