MATLAB: How could I finish the for loop

for loop find

I am writing a for loop. like this,
% 
stations=[1 1 1 2 2 2 3 3 3];
stats=[1 2 3];
datapb=[];
for i=1:length(station(s))
  [row,col]=find(stations(i)==stats(1)); 
  dataps=max(datap(row));
  datapb=[datapb;dataps]; 
end
[DEPTH, ia3, ic3] = unique(datapb,'stable');
%
I would like to obtain three DEPTH by change the stats from stats(1) to stats(3). How could I use two for loop to finish the calculation? Thank you very much in advance!

First thing:
[row,col]=find(stations(i)==stats(1));
This only looks at a single value of stations, so it can only return a single value for row and col. This means that dataps=max(datap(row)); will return every value as max, because it is only comparing one value at a time.
Also, stations is a 1x9 array, so all row values will be 1.
You might try something more like this to get your logic and max values.
for k = 1:length(stats);
 dataps = max(datap(stations==stats(k)));
 datapb=[datapb;dataps];
end
