x = floor(rand(1, 100)*10);
[N, Bin] = histc(x, unqiue(x));
Now you can use sort(N) to find the most frequent elements. Then you can search the corrsponding indices in Bin.

You probably do not need to use both sort _and_ unique: unique does a sort.

To remove the most frequent value, and assuming it is a vector you are working with:
x(x==mode(x)) = [];
