Create a model, get the root architecture, create one variant component, add two choices for the variant component, set the active choice, and find the active choice.

model = systemcomposer.createModel('archModel');
arch = get(model,'Architecture');
variant = addVariantComponent(arch,'Component1');
compList = addChoice(variant,{'Choice1','Choice2'});
comp = getActiveChoice(variant)
comp =
