How can I delete repeated elements? (not unique!)

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

Answer 1

[Iain]

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

[Barbara]

 thank you :) based on what you've sent it works with this one:

 output = input(find(diff(input)))

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])
