what "help clf" produce ?
on octave 3.4.0, clf reset is available:

octave:2> help clf
`clf' is a function from the file /usr/share/octave/3.4.0/m/plot/clf.m

 -- Function File:  clf ()
 -- Function File:  clf ("reset")
 -- Function File:  clf (HFIG)
 -- Function File:  clf (HFIG, "reset")
    Clear the current figure window.  `clf' operates by deleting child
    graphics objects with visible handles (`handlevisibility' = on).
    If HFIG is specified operate on it instead of the current figure.
    If the optional argument `"reset"' is specified, all objects
    including those with hidden handles are deleted.
