I have two matrices as follows.
popx=[52.647 10.912 2.389
52.564 10.911 2.389
52.569 10.912 2.389
52.569 10.912 2.389
52.569 10.913 2.389
52.569 10.913 2.389];
cx=[52.646 10.912 2.389
52.564 10.911 2.389
52.569 10.913 2.403
52.570 10.912 2.389
52.569 10.913 2.389
52.569 10.912 2.389];
Now, I want to split cx into two matrirces as per the following-
- rows which are UNIQUE with respect to popx.
- rows wich are NOT UNIQUE with respect to cx.
Finally, I will again merge these two matrices which will be equivalent to cx (i do not mind if the order of rows are diffferent).
How can I do this?

This might be what you want.
popx=[52.647 10.912 2.389
52.564 10.911 2.389
52.569 10.912 2.389
52.569 10.912 2.389
52.569 10.913 2.389
52.569 10.913 2.389];
cx=[52.646 10.912 2.389
52.564 10.911 2.389
52.569 10.913 2.403
52.570 10.912 2.389
52.569 10.913 2.389
52.569 10.912 2.389];
[~,~,Gp]=unique(popx,'rows');
[~,~,Gc]=unique(cx,'rows');
Hp=histcounts(Gp,1:max(Gp)+1);
Hc=histcounts(Gc,1:max(Gc)+1);
crit1=(Hp==1);
crit2=(Hc>1);
M1=cx(crit1(Gp),:)
M2=cx(crit2(Gc),:)
result=[M1,M2]
