I think Ignacio or Sven probably answered this one already, but 
just to make sure....

The syntax

matrix M = { X1;X2;X3 }

is designed for the case where X1, X2 and X3 are either scalars or 
series, not matrices.  For sticking matrices together 
(horizontally) one uses

matrix M = X1~X2~X3

Sticking matrices together vertically, we're working on!
