Removal of RT_MODEL variables in code generation

I have a question about the usage of reusable function setting in the code interface packaging option for embedded code generation. What i found is that RT_MODEL variable is included in the arguments of the function for the generated code as attached in a file. How can i remove this RT_MODEL variable from the argument?

Hello byungkeuk,

Currently, I am facing the same problem, I want to know how you removed the rt_model from the step and initialize function.

Hi byungkeuk,

Code Reusability allows you to receive model data by function arguments. To do so, it creates a real time model object (model_M).

I think you are trying to create a reusable "function" which can just accept inputs and outputs. You can do so by using a "Nonreusable" code interface and just configuring model Functions by using the "Configure Model Functions" button. This allows you to choose a function prototype. You can select "Model Specific C prototypes" and then choose the input and output arguments of the step function. More information can be found at the following link:

Hope this helps!

Hi Prashant and byungkeuk,

Is there another way? Because if I do try this it changes the initialize() function too, in way that the external Inputs and Outputs disappear.

from this..

void initialize ()
}
   // external inputs
   Model_U.In1 = 0.0;  

     // external outputs
     Model_Y.Out1 = 0.0;
  }

to this...

void initialize ()
}
   // inputs and outputs disappeared   
}

Do I have to add this as 'custom code' by myself, or does initialization works after this change completely different?
