Hi,

I've been looking long and hard for a solution to this issue. It's a seemingly simple problem, I have a Simulink bus with a lot of different signals and I need an efficient way of converting this bus with mixed datatypes to a flat (1D) array of doubles. But I can't get it working to fulfill my conditions.

I have tried everything for stateflow charts with matlab functions, to custom matlab functions with a predefined bus object, but nothing works that is efficient enough that can be Code Generated in a reasonable time.

My current solution (more like hack) includes retrieving the hierarchy of the bus using get_param(hdl,'SignalHierarchy') to get the structure of the bus and then convert that to a list and autogenerate an InBus, Cast and OutBus block for each bus signal. This leads to 5 minutes longer build time which isn't really acceptable for my use case.

Any input is appreciated, thank you :)
