Hi,
MatrixForm[] is wrapped arround your expression if you give
G = MatrixForm[{{1, 2}, {3, 4}}]
than
FullForm[G]
MatrixForm[List[List[1, 2], List[3, 4]]]
Since MatrixForm is only for printing/Output
MatrixForm[] prevent all matrix operations.
Remove the MatrixForm[] and set the Cell | Default Output Format
to TraditionalForm to see the printed matrix.
Hope that helps
Jens
