Good night all,

I hope you call help me with this question.

I have a matrix like this in Matlab.

(...)

Now I want to get the most frequent number in groups of 4 rows. For example;

2012 1 1 0
2012 1 1 1

Perhaps you want the unique() function:

A=[2012  1  1  0
1  1  0
1  1  0
1  1  0
1  1  1
1  1  1];
[C,ia,ic] = unique(A,'rows')

Well, at least it gives you what you asked for, for the matrix you gave. C is exactly what you said the output should be.

Perfect! Exactly what I want, thank you!
