Hello,
I would like to use a custom data type (Simulink.Bus object) for a S-function paramter in a custom S-function. The documentation states that custom data types can be used for S-function parameters [1]:
To register a custom data type recognizable by Simulink, the S-function mdlInitializeSizes routine must register the data type, using ssRegisterTypeFromNamedObject. For example, the following code placed at the beginning of mdlInitializeSizes defines a custom data type from a Simulink.AliasType object named u8 in the MATLAB® workspace. The example then assigns the custom data type to the first output port.
int id1;
ssRegisterTypeFromNamedObject(S, "u8", &id1);
ssSetOutputPortDataType(S, 0, id1);
In addition, you can use the identifier id1 to assign this data type to S-function parameters, DWork vectors, and input ports.
The code snippet in the above-quoted documentation works for output ports (and in a similar way for input ports). Unfortunately, I was not able to use custom data types for S-functions parameters. I simply could not find a corresponding SimStruct functions, like ssSetParameterDataType, in the documentation.
Could somebody poinpoint me to the corresponding entry in the documentation or provide me a brief code snippet?
Thank you!
