MATLAB: Reduce dimension of a vector

arrayMATLABsize;vector

Hello at the beginning of my code i declare a vector
riga_save=save_rig;
where save_rig is 1×14. after some works on the indices at the end of my code i find this:
riga_save =
     2     3     9    10    11    15     0     0     0     0     0     0     0     0
in my code i go to put all zeros in riga_save at the beginning and then i go to replace these zeros with some indices of save_rig…so at the end i find all these 000 given by the oversized, since the vector save_rig is bigger then riga_save. how can i remove the 0 0 0 given by the oversized?
thank you

i've done this:
   app_save=riga_save;
  clear riga_save
for i=1:length(colonna_save)
riga_save(i)=app_save(i);
end
i want to know if there is something with more efficiency.
