[PyMOL] Apply a transformation matrix to a selection

Hi people!

I'm trying to apply a transformation matrix to a few atoms in a
representation. By now I'm using a python script that modify the
position vector directly in the pdb, and then load the new pdb, but I
think that should exist some other way to apply the matrix direct with
the pymol.

Something like

   create a,resi 10
   apply_transformation_matrix a, [[x,x,x,x],[x,x,x,x],[x,x,x,x],[x,x,x,x]]

Or I'm just dreaming?

Thanks!
