Hi,
Doing that I get the following:
Browse[2]> Reduce["+",results]
Error in Reduce["+", results] :
object of type 'closure' is not subsettable
Thanks again!
Kind regards,
Greg

This would collapse it down to just one nxm matrix. Any easy ways to do that? As always, I'd like to avoid a for loop to keep computational time low! Thanks again everyone!
