| Hello!
|
| I like to create from the four matrices A (N1 
rows and N1 columns),
| B (N1 rows and N2 columns), C (N2 rows and N1 
columns),
| D (N2 rows and N2 columns) a new matrix X of the 
form
|
|      A  B
| X =
|      C  D
|
|
| Once A & B and C & D have been merged, the first 
(A & B) and the
| second row (C& D) can be merged in that way by 
applying Join, which is
| not a problem but how can I merge A & B (and of 
course C & D) in
| that way?
|
| Kindly regards,
| Roman.
