Array filter and store into different variables using for loop

Hi, I have an array with multiple columns that I separated into each variable that now contains single column. I then created index filter option and I can filter the array based on certain parameter and exclude out all the other values. The problem I'm having is how can i store the information in multiple variables for later usage using for loop.

for u = 1 : Zr

iz(u) = find(r(:)<div*u); dispx(u) = Qxrs(iz(u)); dispy(u) = Qyrs(iz(u)); X(u) = Xw(iz(u)); Y(u) = Yw(iz(u));

end

So for left side: I want to create index variable iz__ and then based on that index, restore all the values of the array into new variable dispx_, dispy__, X__, Y__. What matlab is stating that I'm trying to store entire array into a single column of x but that is not what I intend to do.
