This is my Data-
[705.7142857 705.7142857 173.4285714 84.71428571 232.5714286 232.5714286 114.2857143 55.14285714 25.57142857 74.85714286 35.42857143 15.71428571 5.857142857 5.857142857].
I want to group same data into 1 group. This is 14*1 matrix where it has 3 pairs(705.7142857 705.7142857, 232.5714286 232.5714286 & 5.857142857 5.857142857) of same value data. So, I want these 3 pairs into 3 groups and rest of them into other 8 groups.
Is there anybody who can help me to code this?

Supposing your data is in vector v then
[~, ~, uidx] = unique(v);
grouped = accumarray(uidx, v, [], @(V) {V});

This worked as I inteded:
y=[705.7142857
705.7142857
173.4285714
84.71428571
232.5714286
232.5714286
114.2857143
55.14285714
25.57142857
74.85714286
35.42857143
15.71428571
5.857142857
5.857142857];
group = findgroups(y);
uniqueGroups = unique(group,'stable');
Thanks :)
