Hi Dominik Kurzmann,
I understand that you are trying to load the control variables from a Variant Configuration into the MATLAB workspace without updating the Simulink model.
You could push the control variables to your workspace without requiring a model update by following the steps mentioned below:
- On the Modeling tab, open the Design section and click Variant Manager.
- In the Configurations tab, scroll down to see the Control Variables section. The section shows the name of the currently selected variant configuration.
- Click on the “Export control variables to workspace(s)” button.
You could also achieve the same programmatically by following the steps given below:
- Get the variant configuration data object
varconfigdata = Simulink.VariantManager.getConfigurationData(modelname);
2. Retrieve a specific configuration
cfg = getConfiguration(varconfigdata, "LinInterExpNoNoise");
3. Check if ControlVariables exists, if yes extract control variables else throw an error.
if isstruct(cfg) && isfield(cfg, 'ControlVariables')
vars = cfg.ControlVariables;
Assign control variables to base workspace
for k = 1:numel(vars)
assignin('base', vars(k).Name, vars(k).Value);
end
