How to match pair of two elements of a matrix with the pair of two elements of another matrix?

I have two matrices with two columns:

A= [1 3; 5 9; 7 6; 10 8]

B = [10 8; 7 6; 70 16; 1 3; 12 34; 5 9; 20 45; 10 8]

I want to match two elements of A matrix with B matrix land find its index number.

Like [1 3] pair want to find in matrix B.

Please give me any suggestion to do this. Thank you.

A= [1 3; 5 9; 7 6; 10 8]

A = 4×2

1 3 5 9 7 6 10 8

B = [10 8; 7 6; 70 16; 1 3; 12 34; 5 9; 20 45; 10 8]

B = 8×2

10 8 7 6 70 16 1 3 12 34 5 9 20 45 10 8

[tf,loc] = ismember(B,A,'rows');
rowindexInA = loc(tf);
rowIndexInB = find(tf);
rowVal = B(rowIndexInB,:);
Tmatch=table(rowVal,rowindexInA,rowIndexInB)

Tmatch = 5×3 table
     rowVal     rowindexInA    rowIndexInB

    10     8         4              8
