How is the FIND_SYSTEM command used with referenced models in Simulink 6.5 (R2006b)?

I would like to know if the FIND_SYSTEM command can be used in Simulink 6.5 (R2006b) to search and get information on models containing reference blocks.

You cannot use the FIND_SYSTEM command by itself in Simulink 6.5 (R2006b) to obtain the contents of a referenced model.

There are two possible workarounds:

1) Use the FIND_MDLREFS command in conjunction with the FIND_SYSTEM command.

For example, to find the relational operator blocks inside all of the referenced models that have the relational operator property set to "==" in the demo model "sldemo_mdlref_basic":

[r, b] = find_mdlrefs('sldemo_mdlref_basic');
load_system(r{1})
rel_blks = find_system(r{1},'FindAll', 'on','BlockType','RelationalOperator','Operator','==')

Note: The last two commands can be used in a FOR loop if you have multiple referenced models.

2) A second possible workaround is to use the MATLAB file submitted in the following MATLAB File Exchange link:
