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

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

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
