Ran in:
It's not exactly clear what the intended logic is, but this is a simple membership test
A=[4 5; 4 19; 5 7; 4 5];
B=[4 5];
if ismember(B,A,'rows')
% calculation 1;
disp('B is a member of A')
else
% calculation 2;
disp('B is NOT a member of A')
end
B is a member of A

I think this works if you want to do a calculation for each member of B.
A=[4 5;4 19;5 7;4 5];
B=[4 5];
for i=1:size(B,2)
if ismember(B(i),A)
calculation1;
else
calculation2;
end
end
