Hi, I'd like to delete repeated elements, but keep it in this way:
Input = [2 2 3 3 4 2 2 5 3 3]
Output = [2 3 4 2 5 3]
With unique, some of these elements disappear. Does exist an other function?
Thx

output = [input(1) input(find(diff(input))+1)]

I don't know such a function, but try this:
Output = Input;
0 = 1;
while i < size(Output,2)
if Output(i) == Output(i+1)
Output(i+1) = [];
else
i = i+1;
end
end

Output = Input([true,diff(Input)~=0])
