hi,
I want code do the following without using for,if let unique_x is a vector
t=1;
for v=1:length(z)
a1=find(unique_x==z(v));
if isempty(a1)
evaluation(t)=z(v);
t=t+1;
end
end
thanks in advance

It would be easier for us to help you if you supplied a small example of self-contained code that runs from start to finish. Specifically, telling us a small example of unique_x and z would help.

I think that you'll want something along the line of the following example:
>> z = [3 5 7] ;
>> unique_x = [1 2 7 8 9 3] ;
>> evaluation = z(~ismember(z, unique_x))
evaluation =
5

setdiff(z, unique_x)
provided that you do not care about the order of the results, and there are no duplicate values in z.
