SLX file format
---------------

Starting in MATLAB version R2012b, SLX is the default file format for Simulink
models.

Learn more about the SLX format at `the Mathworks website <http://www.mathworks.com/help/simulink/ug/saving-a-model.html#btbr7kx-1>`_.

Simulink Library Browser Warning
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

On MATLAB versions newer than R2012b, you may get this warning in the Simulink
Library Browser:

``Some libraries are missing repository information. **Fix**``

Clicking the "Fix" link in the message gives you the following options:

* ``Resave libraries in SLX file format``: this will save the highest level
  library blocks plat_lib.mdl and plat_lib_ext_diag.mdl as .slx files.  The
  underlying linked library models will not be affected.

* ``Generate repositories in memory``: this will update the repository browser
  for the current Matlab session, but does not change any files.  This will
  have to be done each time Matlab is restarted.

* ``Skip (libraries will not be viewable)``: doesn't display the OpenECU
  library blocks in the browser.  To use the library blocks, you have to open
  them by browsing to OE_INSTALL_PATH/openecu/model.

Any of these 3 options are OK to select, and should not affect the
functionality of the models or the generated code.
