Article on Creating Locked and Protected Model Blocks in Simulink

This paper discusses the steps required to make a protected version of a Simulink Block Diagram

This Article contains description on the following:
* What is Simulink and how it is used to model systems
* Creating a sub-system of the model to hide its implementation temporarily
* The purpose of protecting your intellectual property from other users
* Steps that are employed in creating a permanently locked, protected version of the model
* How to use a protected model block in another Simulink model

This file also contains Simulink model files that are used in this process of protection and referenced in the Article using snapshots
