Hello everyone
I have a mXn matrix called Theseis that it has the above elements in spread around the table and in any other point has 0.

2614 2646
2615 2645
2615 2646
Is there a way to find which elements are the same(except the zeros) or guite the same(eg these are guite the same:
2613 2646
2614 2646
2615 2645
2615 2646
) and delete them and leave only one of each group. eg the new maytix will be
1056 2631
1419 3663
.......................etc

The answer for everyone who wants it is quite simple!
for i=1:x-200
for j=1:y-800
if mean2(Pattern_epikef==Foto2(i:i+23,j:j+75) ) >= 0.87
Theseis(i-2:i+2,j-2:j+2) = 0;
Theseis(i,j)=1; % ana vreis omoio kommati dose 1 ston pinaka
end
end

let say you have 2 vector A ,B (like your columns there) you can do something like : [C, ia] = unique(A); for k = 1:length(ia) D(k)=B(ia(k)) end then do the same with D with respect to C and you are done. for M x N you can extend this to run on all the columns ..,
