Form a matrix out of a table

[rolandimm]

Hi,

I've got the following question:
If I had three variables
- x: which can have the values; 1, 2, 3 or 4
- y: which can have the values; 1, 2, 3 or 4
- z: is a dummy variable 0/1.

and I do the following command:

tabulate y x if z == 1

This gives me 4*4 table. Is it possible to create directly a matrix (4*4) out of this table without typing all the 16 values by hand?

Hope someone can help

thanks a lot,
roland
