how to make Si111(sqrt3×sqrt3)R30◦

[Saleem Ayaz KHAN M . Sc .]

Dear Sir
Greetings, I want to make  Si111(sqrt3×sqrt3)R30◦ surface using octave.
I loaded the Si basic structure to octave and prepared Si111 surface. See the 
commands
 s=loadstruct("Si.struct")
s1=makeprimitive(s)
s2=makesurface(s1,[1 1 1],1,30.0,30.0)
savestruct (s2, "Si111-surface")

Now I have no idea how to move the origin of Si111 to construct 
Si111(sqrt3×sqrt3)R30◦. See the plot and structures in attachment.
please help me.


regards
Saleem
