MATLAB: Remove repeating variables and replacing them

duplicates

Ex: In the array

x=[4 4 5 5 1 2 2 3 3 3 4 5]

, i want to eliminate all repeating elements and retain non-repeating elements

(4, 5,1,2,3,4,5)

i.e., If

x=[4 4 5 5 1 2 2 3 3 3 4 5]

, answer should be

x=[4 5 1 2 3 4 5]

Best Answer

x = x([true diff(x)~=0])

MATLAB: How to remove duplicates in an array

 >> x=[1 2 2 3 3 3 4 5];
 >> y = zeros(size(x));
 >> for i = 1:length(x)
   y(i) = sum(x==x(i));
end
 >> for i=length(y):-1:1
 if(y(i)>=2)
 x(i)=[];
 end
 end
 And your output will be 
 >>x
   1     4     5
