Automatic c++ code generation with simulink coder

Two questions:

Question One: How can I avoid the initialize function and introduce the initialize code into the constructor?

Example:

instead of

void PIDModelClass::initialize()

{ rt_InitInfAndNaN(sizeof(flt64));

(void) memset((void *)(&PID_M), 0, sizeof(RT_MODEL_PID_T));

(void) memset((void *)&PID_DW, 0, sizeof(DW_PID_T));

}

// Constructor

PIDModelClass::PIDModelClass()

{

// Currently there is no constructor body generated.

}

I want this to see

// Constructor

PIDModelClass::PIDModelClass()

{ rt_InitInfAndNaN(sizeof(flt64));

(void) memset((void *)(&PID_M), 0, sizeof(RT_MODEL_PID_T));

(void) memset((void *)&PID_DW, 0, sizeof(DW_PID_T));

}

Question Two: How can the class declartion for the model include inheritance from a parent class (here Filter)?

// Class declaration for model PID

class PIDModelClass : public Filter

{

// public data and function members

public:

// model initialize function

void initialize();

// model step function

void step();

// model terminate function

void terminate();

// Constructor

PIDModelClass();

// Destructor

~PIDModelClass();

// Real-Time Model get method

RT_MODEL_PID_T * getRTM();

// private data and function members

private:

// Block states

DW_PID_T PID_DW;

// Real-Time Model

RT_MODEL_PID_T PID_M;

};

Hi Markus,

I have the same problem as Klocwork generates an error when it does not find the input / state / output variables initialized in the constructor.

Have you found a solution in the meanwhile?

Thank you!

I talked to various technicians during a seminar in Munich and couldn't get a solution from the matlab coder itself.

The only workaround was a parser script that alters the generated code. But this is not an appropiate solution for

our development team.

Thank you for your reply. In this case the only other solution looks TLC code customization.
