you can represent an m by n matrix with an m times n length vector using 
the following scheme:
   matrix[x][y] == vector[x*m+y]

sorry, tha should be matrix[x][y] == vector[x*n+y].

You may want to check out the vectorial opcodes ...

The linear algebra opcodes are, among many other things, matrix opcodes.
