MATLAB: How to connect bus signal with different data size using multiport switch

Question

Hi,

I have two subsystems, and I want to minimized the data size for the signal that is been transfered in between the subsystems. The following figure shows the ideal case. When Constant1 = 1, the first signal with size {1} is transmitted; when Constant1 = 2, the second signal with size {2} is transmitted; Unfortunately, there will be error pop-up regarding to data size mistmatching in this model, which is attached. How could I solve this error or is there other approach to minized this data size. Noted that the constant value should be constant during the simulation.

Regards,

Andy

Answer 1

I made a number of changes to your model, most importably was to remove mux blocks. Mux blocks should not be used. Use Vector/Matrix concat blocks to create vectors/matrices, use Bus Creater blocks to create buses.
