Custom MATLAB file

Update active configuration parameters of parent model by using file containing custom MATLAB code

• 

Libraries:
Embedded Coder / Configuration Wizards

Description

When you add a Custom MATLAB file block to your Simulink^® model and double-click it, a custom MATLAB^® script executes and configures model parameters that are relevant to code generation. Set a block parameter to invoke the build process after configuring the model.

After you double-click the block, open the Configuration Parameters dialog box to see that the model parameter values have changed.

Use the example MATLAB script, matlabroot/toolbox/coder/simulinkcoder_core/rtwsampleconfig.m with the Custom MATLAB file block. Adapt the script to your model requirements. The block and the script provide a starting point for customization. For more information, see Create a Custom Configuration Wizard Block.

Note

To provide a quick way to switch between configurations, you can include more than one Configuration Wizard block in your model.

Parameters

Configure the model for — Configuration objective

Custom (default) | ERT (optimized for fixed-point) | ERT (optimized for floating-point) | GRT (optimized for fixed/floating-point) | GRT (debug for fixed/floating-point)

Objective for updating the active configuration parameters of a parent model by using a predefined MATLAB script.

Configuration function — Custom MATLAB script

rtwsampleconfig (default)

Predefined or custom MATLAB script that updates the active configuration parameters of the parent model.

Dependencies

This parameter is only used with this Configuration Wizards block. To enable this parameter, set Configure the model for to Custom.

Invoke build process after configuration — Initiate build process

off (default) | on

If selected, the predefined script initiates the code generation and build process after updating the configuration parameters.
