How to use an if else statement to choose one specific variable?

Hi

I have a variable 'tf', in the form of 1s and 0s.

tf= [1 0 0 0 1 1 0 1 1];

Now there is this 2nd variable which is tf2, as:

tf2=[12 15 16 17 18 19 20 30 48];

I wan to do is, if tf==1, save the corresponding value of variavle tf2 in X, and when tf==0, save the corresponding values in the variable Y. by using the for loop and if else.

e.g for tf==1; X=[12 18 19 30 48]; and Y=[1516 17 20];

How i can do this in MATLAB. Any help will be appreciated. :)

X = tf2(tf==1);
Y = tf2(tf==0);
