Thread Subject: Identify vector values >9 and subtract 10

Hi, just need a little help, I have no idea how to go about this.
If i was given an arbitrarily sized row vector, [1 18 4 5 9 14 11] in
this case. How would I identify all the values that are bigger than 9,
subtract 10 from them and add 1 onto the previous value in the row?
Thanks =)

one of the many solutions

     v=[1 18 4 5 9 14 11];
     ix=find(v>9);
     v(ix)=v(ix)-1;
     ix=ix-1;
     v(ix)=v(ix)+1;
