How to get variables needed for Simulink model?

I have a Simulink model and a large workspace from which I need some variables for the model. I would like to load only those variables that are needed, and not the whole workspace. How can I get the list of variables that are required for the model?

See the use of Simulink.findVars at this doc page. Also this blog post might be useful.

filename = 'yourMatfile.mat';
yourVariables = {'X','caption'};
S = load(filename,yourVariables{:})
