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

Accepted answer

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.

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_xandzwould help.## huda nawaf (view profile)
