Apply specified variant configuration to model

Since R2022b



Simulink.VariantManager.applyConfiguration(model,Configuration=configName) applies the variant configuration specified by configName to the model model and any referenced components in the model hierarchy.

The variant configuration named configName must be present in the VariantConfigurationData object associated with model. The operation exports the variant control variables defined in the specified configuration to the base workspace or data dictionary used by the model.

This function allows you to quickly switch the variant configuration for a model. The function does not validate the configuration. To validate and activate a model using a specific configuration or using the currently applied configuration, use the Simulink.VariantManager.activateModel function.


To use this function, you must install the Variant Manager for Simulink® support package.

Open the model slexVariantManagement.

model = "slexVariantManagement";

The model has multiple named variant configurations stored in the variant configuration data object vcd associated with the model.

You can compile or simulate the model for a configuration after applying the configuration to the model.

% Apply the configuration LinInterExpNoNoise
% Compile the model
% Simulate the model
