Load a model that has a variant configurations object attached.

load_system("myModel");

Export the variant configurations object to a MAT file.

Simulink.VariantManager.exportVariantConfigurations("myModel", ...
    FileName="exportedVCD.mat");

Load the exported MAT file and access the variant configurations object.

data = load("exportedVCD.mat");
vcdoName = get_param("myModel","VariantConfigurationObject");
varConfigs = data.(vcdoName)

Load a model that has a variant configurations object attached.

load_system("myModel");

Export the variant configurations object to a MATLAB® script. If no extension is specified, the function defaults to .m.

Simulink.VariantManager.exportVariantConfigurations("myModel", ...
    FileName="exportedVCD");

Run the exported script to recreate the variant configurations object in the workspace.

run("exportedVCD.m");

Input Arguments

collapse all

Name of the model, specified as a character vector or string scalar. The model must be loaded before calling this function, and the model must have a variant configurations object associated with it.

Example: "slexVariantManagerOverview"

Output filename or path, specified as a character vector or string scalar. The filename must be a valid MATLAB identifier.

Supported file extensions:

  • .m — Export a MATLAB script that recreates the variant configurations object when run.

  • .mat — Export the variant configurations object to a MAT file.

If no extension is specified, the function defaults to .m. If no directory path is specified, the function saves the file in the current folder.

Example: "exportedVCD.mat"

Tips

To recreate the exported variant configurations object, run the exported .m script or load the exported .mat file using the load function.
