I would like a function to remove the duplicate values, but one that removes the duplicate value as well.

I would like a function to remove the duplicate values, but one that removes the duplicate value as well.

That is, if I have a vector A = [ 1 2 3 4 5 6 6 6 7], I would like to get an output equal to B = [1 2 3 4 5 7].

Note that I want to get the same order as the original vector, I don't want it to organize.

That is, if I have a vector A = [7 8 9 6 5 2 2 2 1], in the end I would like to get a vector equal to B = [7 8 9 6 5 1].

USing the functions in

https://www.mathworks.com/matlabcentral/fileexchange/78008-tools-for-processing-consecutive-repetitions-in-vectors

A = [7 8 9 6 5 2 2 2 1];

G=groupConsec(A);
[~,~,len]=groupLims(G,1);
L=len==1;

B=A(L(G))

B =

7 8 9 6 5 1

But my numbers don't necessarily have to be consecutive, I want it to work in any case

Even easier:

A = [7 2 8 9 6 5 2 1 2];

G=findgroups(A);
L=accumarray(G(:),1)==1;

B=A(L(G))

B = 1×6

7 8 9 6 5 1
