For e,g
A=[0 1 1 0;
0 1 0 0]
i have selected A(1,2), A(1,3), A(2,2) for use , i want to know that which pair is adjacent to other ?

That's not what I asked. I want to know if you consider A(2,2) "adjacent" to A(1,3) because there is a path of 1's connecting them. If so, you can simply use bwlabel.

If you have two locations: row1, col1 and row2, col2, then they are immediately adjacent (1 layer away) if
if abs(row1-row2) <= 1 && abs(col1-col2) <= 1
% Adjacent
else
% Not adjacent
end
