ask for matlab script to give only the entries not in other file

Hi

Suppose I have two files X and Y. Both have some entries for example

x:

1222 1232 3310 2223

y:

5555 1222 3310 1212

I want a a script to go through all entries at X, scan it, and if the the entries not present at Y print it to new file Z, so that Z contain only the entries that are in X not in Y like the following:

Z:

1232 2223

How can I do something like this ? ?

x=[1222 1232 3310 2223];
y=[5555 1222 3310 1212];
setdiff(x,y)
