As long as you're simply doing what you asked (to find a single scalar value in a vector), you can use any(A==B) like this:

A=[2 5 6 3 ];
B=3;
if any(A==B)
  message = sprintf('The B value of %d is in A.', B);
  uiwait(msgbox(message));
end

Needless to say, you can use the B1 variable instead of B.

You need the ismember() command.
