Evan,
actually it seems to me that the attached code does what you intend  
to do.

 >> f=@(x) (x+pi)
f =

@(x) (x + pi)

 >> handletest(f,ones(3,1),3)
ans =

    10.425
    10.425
    10.425


I would be interested in knowing whether it gives any performance  
improvement
when applied to your case (I suspect not).
