mutual array between two matrix

Hi everyone I need to eradicate mutual arrays between matrix Y and matrix Z and put the rest of Z in another matrix to make more clear:
Y=[8,4,2,1,7,3,5,6];
Z=[5,2,1,6,8,3,4,7];
Now I need to choose for example '2' and '7' in Y and consequently eliminate '2' and '7' in Z and keep the rest of Z (5,1,6,8,3,4) in for example R
can someone tell me how to code that?
thank you all in advance.

This question is not that clear to me. What are the conditions to pick '2' and '7' in Y?

Two ways:
R = setdiff(Z,Y);
That'll remove every element of Y that appears in Z.
Aleternatively, use this approach
R = Z;
eliminate_this = Y(1);
R(R == eliminate_this) = [];
You'll need to add in the right loops, and index Y correctly.

k = [2, 7];
t = ismember(k,Y);
if all(t)
R = Z(~ismember(Z,k));
end
