Can a bus be used with an output port of a matlab s-function?

Hi

I'm writing a Matlab s-function and would like to output a bus. All I've been able to find regarding outputting a bus from a s-function is for c/c++ s-functions. I would rather not have to go down that road if I don't have to. Any suggestions would be appreciated.

I'm using 2011b

Thanks...

Mike
