How to compare two date vectors?

Dear all, I have two date vectors, which I converted with datenum. They had have the string format dd.mm.yyyy. The one vector control is a 3288*1 vector and the other one t is 2753*1 vector. So, I want to check wich dates of control are in t! And if one date of control is t, then matlab should make a 1 in count! Thus I can identify the matches! I tried it with the following order:

count = zeros(length(control), 1);

for i = 1:length(control)
    if control(i,1) == t(1:end);
        count(i,1) = 1;
    end
end

But it is not working. After the loop there still only zeros in count! What is wrong or what do I have to add???

Thank you in advance!

I think you will find the ismember() command to be what you need. If I understand correctly, I think you want:

count = ismember(control,t)

but certainly test it for yourself.
