LiveLink™ for Simulink® does not depend on LiveLink™ for MATLAB®, but the two products work together. If both products are installed, you can choose to start either product and work seamlessly with the LiveLink for MATLAB wrapper functions and the Simulink cosimulation environment. If a floating network license (FNL) is used, it may be important which product is started first, because a license for the first started product is checked out from the license server. For example, if you first start LiveLink for Simulink as described in Starting COMSOL® with Simulink® you will check out a license for LiveLink for Simulink. If you then later in that session use functionality that requires a license for LiveLink for MATLAB, a license for LiveLink for MATLAB will also be checked out at that time.
