This is as far as I have gone.

The ishandle function should return a result for each member of it's input with 
the same shape as it's input.

As I am limited to the m-file caste, I hope one of you guys in the upper c++ 
caste can take this on ;-)

If this really is the same problem as the one you posted the link to, than I 
expect my conclusion as to what the problem is that I've encountered is quite 
overly simplified.
