Hello,
You can use enumerated data type in C-MEX S-Function by defining same data type with MATLAB and S-Function.
To use enumerated data type in S-Function, you need to use ssRegisterTypeFromNamedObject method to resister the data type from MATLAB/Simulink into S-Function. Sample files can be downloaded below. To execute the model, execute following command first, and then simulate the model.
>>mex enumExample.c
In this case, we use the OnOff.m enumerated data type class for the registration. More on this S-function method can be found here:
More on creating these custom data types in MATLAB can be found here:
After the type is registered, you can use the "ssSetInputPortDataType" method to set the type accordingly:
if (ssGetSimMode(S) != SS_SIMMODE_SIZES_CALL_ONLY) {
DTypeId dataTypeIdReg;
ssRegisterTypeFromNamedObject(S, "OnOff", &dataTypeIdReg);
if (dataTypeIdReg == INVALID_DTYPE_ID)
return;
ssSetInputPortDataType(S, 0, dataTypeIdReg);
}
See example enumExample.c attached to know more about using enumerate data type in C-MEX S-Function.
