Hello,

I have three column vectors of same sizes. I want to remove values 8 9 10 from the one vector (B) such that the subequent values in other two vectors (A and C) also get deleted. Similarly, I want to remove values 8 9 10 from vector C such that the subsequent values in other two vectors (A and B) also get deleted (means whole row gets deleted). How to perform this task?

在 MATLAB Online 中打开

mask = ismember(YourArray(:,2), [8 9 10]) | ismember(YourArray(:,3), [8 9 10]);
NewArray = YourArray(~mask, :);

These A,B,C are three different variables in my MATLAB workspace. And rather than using mask (means using the first line of code and getting logical), I want these three separately. Becuase for my further work I'm using them separately. Result should be like:
