Ok, job done.
I used the submatrix block for the inputs and the concatenate block for the outputs.
Using the submatrix block you can select the first position of the vector to feed the actual cell, and using another one and selecting from position 2 to the last will decatenate/discatenate the vector properly.
It will look like this:
----[submatrix block u(1)]---- (to drive actual block)
Ain ----
----[submatrix block u(2:end)]---- Aout (to the next block)
In the inputs array, you must add one dummy value at the end in order to avoid an error in the last block because the submatrix. Remind to initialize the outputs vector in the first block as well.
Cheers!
