Reduce dimension of a vector

Hello at the beginning of my code i declare a vector
riga_save=save_rig;
where save_rig is 1x14. 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 would use find inside riga_save to extract the nonzero indices.
However, to answer the question you actually asked, you can do this:
riga_save = riga_save(riga_save>0);
This is also an example of logical indexing!
