Syntax

void model_initialize(void)

Description

void model_initialize(void) is a generated C or C++ entry-point function called one time to execute the initialization code for a Simulink® model. This function is not intended to reset the real-time model data structure (rtM) for a model.

The generated calling interface of the initialize entry-point function for a model differs depending on the Language and Code interface packaging parameters. For more information, see Code interface packaging.

To preview and customize the name of a generated C initialize entry-point function an Embedded Coder® license is required. To preview the function, open the Code Mappings editor and click the Functions tab. To customize the function name, in the Function Name column click and edit the spreadsheet directly. To customize the function using a template, in the Function Customization Template column select a template to apply to the function. For more information, see Configure Names for Individual C Entry-Point Functions, and Configure Default Code Generation for Functions.

To view the generated initialize entry-point function, open the Code view or Code Generation Report and examine the source code for your model. For more information see, Analyze Generated Data Code Interface Report.

Note

Do not confuse model_initialize with other initialization functions that might be generated for referenced models, such as model_Init. Those initialization functions do not appear in the Code Mappings editor and are not customizable.

This example shows the basic workflow for how to configure, customize, generate, and examine an initialize entry-point function.

  1. Open a model.

  2. Select a coder. In the Apps gallery, click Simulink Coder or Embedded Coder.

  3. Set model configuration parameters Language and Code interface packaging.

  4. (Embedded Coder only) Customize the function. Using Embedded Coder, you can customize the name of the initialize entry-point function.

    • Open the Code Mappings editor.

    • Click the Functions tab.

    • In the Function Name column, enter a name for the function.

  5. Generate code.

  6. Examine the generated code. In the Code view, verify that the generated initialize function appears with the expected name and parameters.

Input Arguments
