<h2>
The main library <i>FDCLIB</i>
</h2>
<p>The library <i>FDCLIB</i> is the main portal to all blocklibraries and models in the FDC toolbox. A complete list of these blocklibraries and systems can be found below. In order to reach any one of these systems or libraries, it is necessary to double-click the corresponding block in <i>FDCLIB</i>.</p>
<p>If you want to edit <i>FDCLIB</i>, or any other Simulink library from the toolbox, it is necessary to <i>unlock</i> the library first. However, great care has to be taken to not inadvertently break library links for any blocks or subsystems which are used in other models or by other blocks. Be especially careful not to delete or rename blocks inside libraries, unless you are absolutely sure what you're doing. And, as always: backup first! See the Simulink user-manual for more information on how to deal with blocklibraries.</p>
