Corresponding values between two matrices

Hello,

I have two matrices of different sizes. Please see attached .mat files containing the matrices. Matrix A = [3168x2] and matrix B = [14x1].

The 14 values contained in the first column of matrix B are contained somewhere in the second column of matrix A. I need to identify which rows in A are these valinues contained and also extract the values contained in the first column for these rows.

Any suggestions?

Thanks in advance.
