MATLAB: How to use nested structures in the generated code

Question

How can I use nested structures in my generated code?

I would like to use a few nested structures to capture most of the data used by my model, but Embedded Coder is splitting it into multiple separate variables.

Answer 1

The attached files provide two examples of using nested structures in Embedded Coder generated code. Open the "struct_csc_param_init.m" script to see how the nested structures are set up and run it to observe the resulting generated code.

The first example produces a nested structure in the generated code from separate variables in the Base Workspace using the Struct Custom Storage Class.

Here is a link to the MATLAB Documentation describing the "Struct custom storage class"

The second example produces a nested structure in the generated code based on a nested structure in the Base Workspace.

Both example use the "Simulink.Parameter" object as a way to control the format of the generated code.

Here is a linke to the MATLAB Documentation describing the "Simulink.Parameter" object.
