I’m using Line scripts version 1.0.0 and I'm trying to run LQN Examples(CQN_analysis_1.m, example_CQN_Cox_analysis_1.m, example_CQN_Cox_RE_analysis_1.m, example_CQN_Cox_REPH_analysis_1.m, example_CQN_RE_analysis_1.m )
in MATLAB R2013a but I always get the warning ” Warning: No LQN definition has been found. Performance metrics at entry level will not be computed.”
and the result doesn't Show up in Screen.
Please Help me to run these examples.
Hi Tasabeeh,
This warning is normal when using the LINE scripts to solve a CQN model. As LINE solves LQN models, it can provide more detailed metrics when an LQN definition is provided, as done for instance in the "example_LQN_1" script. In the examples you mention, the CQN models are not associated to an LQN model, and thus the metrics computed are all at the CQN level. When you execute these examples, all the metrics computed are in the output arguments, which are described in the help of each of the "analysis" scripts used in the examples. For instance, in example_CQN_Cox_analysis_1, the script used for analysis is CQN_Cox_analysis, if you type "help CQN_Cox_analysis" in the MATLAB command window, you will obtain the description of these output arguments.
Hope this heps.
Best wishes,
Juan

Thank you very much for clarify that issue, but I get Errors when running these Examples ( example_LQN_1.m, example_LQN_2.m, example_LQN_3.m and example_LQN_4) which is
"Error in readXML_CQN (line 21)
if nargin == 1; verbose = 0; end
Error using lqn.readXML_CQN
Output argument "entryGraphs" (and maybe others) not assigned during call to
"C:\Users\Tasabee7\Documents\MATLAB\LINE_v100_src
(1)\models+lqn\readXML_CQN.m>readXML_CQN".
Hi Tasabeeh,
The error message says that the XML file containing the LQN model cannot be found. Can you please check that the file is in the path indicated by the error message? The "data/LQN/ofbizExample.xml" file is part of the "src/examples" folder, so if you checked out or downloaded the whole release, this and other example files should be in the same location.
A possible source of this error is that the example scripts were copied to a folder (apparently in this case to MATLAB's default folder) without copying the accompanying "data" folder that contains all the supporting data files.
Best wishes,
Juan
