Do you want explode (in: 9 nested matrices -> out: 9 indipendent matrices) or implode the matrix (in: 9 nested matrices -> out: 1 big matrix)?

In the 2nd case you can use for loops and stack() or augment() functions.

I tried to be a bit general, the procedure works for arbitrary block structures as long as the dimensions of the submatrices fit.
