Details:

If you have an undefined variable a 
settig a(3)=4 yields a vector padded with 0's. 
Likewise for a(3,4)=true. 

I also have the impression, that arrays of objects 
behave a little the same: 
Assume pn is a class and a constructor, 
a(3)=pn(4) seems to perform padding with pn(). 

If so, this should be documented. 
I do not know how matlab acts in this case.. did not find docs.
