Hi
Lets say, I have an array with indices like this:
a = [11 12 13 25 26 55 56 57]
Is there a nice way of grouping them into three (in this case) groups based on how close they are?
a1 = [11 12 13]; a2 = [25 26]; a3 = [55 56 57]
Best,
Dawid

If your array is sorted
>> c = mat2cell(a,1,diff(find([true diff(a)>5 true]))); c{:}
ans =
11 12 13
ans =
25 26
ans =
55 56 57
