C Construct

float myParams[5]= {1.0F,2.0F,3.0F,4.0F,5.0F};

Procedure

1. Create the ex_param_array model by using a Gain block.

2. In the model, select the Gain block. In the Property Inspector, set the value of the Gain parameter to myParam.

3. Next to the parameter value, click the action button (the button with three vertical dots) and select Create.

4. In the Create New Data dialog box, set Value to Simulink.Parameter ([1 2 3 4 5]). Click Create. A Simulink.Parameter object, myParam, appears in the base workspace. The Gain block uses the object to set the value of the Gain parameter.

5. In the Simulink.Parameter property dialog box, set Storage class to ExportedGlobal. Click OK.

With this setting, myParams appears in the generated code as a separate global variable.

6. Set Data type to single. Click OK.

7. To build the model and generate code, press Ctrl+B .

Results

The generated source file ex_param_array.c defines and initializes the global variable myParams.

/* Exported block parameters */
real32_T myParam[5] = { 1.0F, 2.0F, 3.0F, 4.0F, 5.0F } ;/* Variable: myParam
