Hi,
I have a simple state-space function that is suitable for input data size of 1 (u1), as indicated in Fig.1. If my input is in form of an array (u1, u2, ... uN) I could use demux and more number of state-space blocks to acheive the same idea, as indicated in Fig.2. However, with known the size of input, how can I implement the same state-space to the input array without manually adjusting the number of state-space blocks? Matrix ABCD should be the same.
Fig 1: SISO
Fig 2: Array input manual adjust

You should not duplicate the State Space block. The size of A, B, C and D should all match properly to the number of states X, the number of input U and the number of output Y.

I think I found a way. Just simply consider them as systems in parallel and make larger ABCD martix with zeros.
