MATLAB: Regroup identical coordinate pair

Question

Hi everyone,

I've got vectors like this corresponding to the coordinates of a point:

X = [1;1;8;5;5;6]

Y = [2;2;5;6;6;7]

and would like to regroup points that have the same coordinates and have the following results :

R_X = [1;8;5;6];

R_Y = [2;5;6;7];

Are there any functions or way to concatenate that would help me to do that ?

Thanks

I have no idea what your objective is, however the unique function will produce the result you posted:

RX = unique(X,'stable')
RY = unique(Y,'stable')

producing:

RX =
     1
     8
     5
     6
RY =
     2
     5
     6
     7
