My usual computer is in for repair. My second machine is PPC based and  
is only able to run Matlab R2007b. I had to add the 3rd line below to  
run your script, but the results are not correct.

??? Error using ==> set
Value cell array handle dimension must match handle vector length.

But this does work

>> ans =
     0     1     0
