I don't think you can bootstrap with whole matrices. 
Or at least you can't -bootstrap- with whole matrices. 

That is a Stata problem, even if it may be 
complaining about something different. 

But I guess there is a conceptual problem in any 
case, unless you can point to a literature in which this makes
sense as a species of bootstrapping problem.
