MATLAB: How to find intersection point or value between two array???

arraymatrix array

I have two array as A and B, where,
A=[1.2222 1.2233 1.3344 1.3354 1.4354]
B=[1.1123 1.2234 1.3254 1.4892 1.5678]
I want 2nd element of A and B to intersect but as A's value is not exact equal to B i am not able to plot my graph. as, A's 2nd value is 1.2233 and B's 2nd value is 1.2234 which is almost equal so i want to put a condition as to search equality till 3rd value after decimal.
