    % This block solves the pressure points optimization problem every simulation step. You can enter multiple pressure points (i.e. coordinates with required pressure) as column vectors.

    % This template includes most, but not all, possible properties,
    % attributes, and methods that you can implement for a System object in
    % Simulink.
