hi everbody, I try to identify similar rows in a matrix. I have tried this but it works only wenn the similar rows are next one to another.
t= [1 2;2 3;4 5;5 4;8 7;6 9]
for i= 1:length(t)-1
if t(i,:)==t(i+1,:)
disp('one Match');
else
disp('no match');
end
end
I think the command ismember can do that but I don´t realy know how to implement it.

What do you want to know exactly?
  1. How many rows are identical to row 1?
  2. For each row, how many rows are identical to it?
  3. For each row, which rows are identical to it?
  4. etc.
I am pretty sure you can use UNIQUE and/or ISMEMBER and/or HISTC.

have you tried the function unique with the option 'rows'?
