OMNeT++ modules which either interface the MATLAB-API and translate the messages into the OMNeT++/INET domain (or the other way around), or which support you in building your own Cyber-Physical-Networks.
NcsContext provides a mechanism based on subclassing to push configuration parameters to the MATLAB domain, e.g. to run parametric studies.
The subclassed module CoCpnNcsContext might give you some insights on how to add your own parameters.
