MATLAB: Mux/Demux for physical signals

Question

Hi!

Given a physical signal vector, how can I split up the vector into its components? That would be something like Mux/Demux for physical Signals.

Example:

inVector = {[1, 2, 3], 'm'};

outScalar = {1, 'm'};

outVector = {[2,3], 'm'};

What I could do ist to use PS-Simulink-Converter → demux (→ Mux foroutVector) → Simulink-PS-Converter. But in this case I get an error creating a composite component of it.

Probably I could create a custom component for splittin the signals up, but that seems a bit cumbersome to me.

Hello Christian,

you are unfortunately correct in that you must create your own mux and demux blocks for simscape physical signals. There is a simscape bus, but it only works for standard bi-direction physical connections, and does not support physical signals. If you have the simscape electrical toolbox, it does have some prebuilt mux and demux options built in for the converters.
