How to change the positions of elements in a vector?

Hi all, I need to find all the components of a vector that are equal to 3 and move them at the end of the vector. Any suggestion? Thanks

Answer 1

[Guillaume]

v = [v(v ~= 3), v(v == 3)];  %assuming a row vector. If column vector replace , by ;

Answer 2

Using the find() function you can do this very easily.

    [R,c]= find(myVector==3)

This gives you the positions of the elements which are equal to 3. Once you have this you can easily reorder. Hope this helps

Thanks but then how can I move them to end? It is a long vector I can not do this one by one..

The answer by Guillaume works. I would not have done it As elegantly as that answer
