Join repeated continuous elements of a vector

Hi, is there a simple method to join repeated continuous elements of a vector in Matlab?
For example if the input is:
in = [1 1 1 2 2 3 6 6 6 1 1 1 4 4 4 2 2 2 6 4 4]
how can i get
out = [1 2 6 1 4 2 6 4]
Note that since 3 is not repeted, it is not in 'out' vector. Same for the only 6.
thanks !

No, there is no simple method. There are some methods that take a few lines.

in = [1 1 1 2 2 3 6 6 6 1 1 1 4 4 4 2 2 2 6 4 4];
i = 1;
count = 1;
out = [];
a = in(1);
while i < length(in)
i = i+1;
if in(i) ~= a
count = 1;
a = in(i);
else
count = count + 1;
end
if count == 2;
out = [out,a];
end
end
disp(out)
