You can use the “Initialization function” to initialize parameters and environment settings that are specific to the model. You can initialize all the variables used in the model parameters.

You can follow the below steps to initialize variables:

1. On Modelling tab, click “Model Settings” arrow
2. Then select “Model Properties”.
3. In the Model Properties dialog box, the model “InitFcn” callback is on the “Callbacks tab”

Here is the documentation link for the “Initialization function”: https://www.mathworks.com/help/simulink/ug/initialization-function.html
