How to identifiy similar rows in a matrix ?
Show older comments
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?
- How many rows are identical to row 1?
- For each row, how many rows are identical to it?
- For each row, which rows are identical to it?
- etc.
I am pretty sure you can use UNIQUE and/or ISMEMBER and/or HISTC.
