A = [1,2,2,3,3,4,5,5,5,6];
value_to_remove = [2,3];

I have an array A, which contains some duplciates. I want to remove part of these duplicates, i.e. remove duplcates of 2 and 3, but leave duplicates of other elements unaffected.

The desired output is:

desired_output = [1,2,3,4,5,5,5,6];

Does someone know how to do this in a simple way?

在 MATLAB Online 中打开

After using that array of elements to value_to_remove .

A = [1,2,2,3,3,4,5,5,5,6];
value_to_remove = [2,3];
is_repeting=zeros(1,length(value_to_remove));
index=[];
for i=1:length(A)
    for j=1:length(value_to_remove) %To get the index of elements to remove
        if A(i)==value_to_remove(j)
            if is_repeting(j)>0 %If it had occured once already
                index=[index i]; %Save the index
            else
            is_repeting(j) =is_repeting(j) +1 ; %Otherwise increase the count for that term
            end
        end
    end
end
B=[];
for i=1:length(A)
    if i~=index(1:end)
        B=[B A(i)];
    end
end
B  %Will display required contents of A if put without semicolon . The required matrix.
