Why do you ask for 2 vectors? Whould the pattern in one vector be considered in the other one? Or are they independent from each other?
Can the same value appear at multiple locations, but should be accepted then? In other words, what is the wanted output for:
v = [1, 1, 2, 2, 2, 1]
? If it is [1,2,1], you can use the fast https://www.mathworks.com/matlabcentral/fileexchange/41813-runlength:
v = RunLength(v);
Or:
function x = NonRep(x)
if ~isempty(x)
x = x([true; diff(x(:)) ~= 0]);
end
end
c = NonRep(c);
