Hello, I have a question about setdiff. I have three variables X ,Y, p. I need to find elements of Y excluding elements of p and corresponding elements of X (corresponding to Y). I ran the following (Both X and Y have same number of elements).

 y=setdiff(Y,p); 
 x= X(setdiff(Y,p));  this doesn't work. Any solutions?

Thanks,

Bharat

在 MATLAB Online 中打开

x = X(~ismember(Y,p));

[~,ii] = setdiff(Y,p);
x = X(ii);
