Hi reader,
I have made a Simulink model in Matlab 6.5.1. I tried running it in R2008 and R2010 but it doesn't run properly. It starts showing error when I run the same model. While the same model runs in 6.5.1.
(To be specific it shows error with lqry command in higher versions)
Can somebody guide me on this? Also On which other version shall it possibly run?
Thanks

Do you have the Control System Toolbox installed and licensed with those later MATLAB versions? http://www.mathworks.com/help/toolbox/control/ref/lqry.html

Yes I have that all in my R2010. Even it starts running the scripts associated with that simulink file. But then shows error.

It says me to tune the values of Q and R. However with the same values of Q and R it runs in lower version. Q and R matrices are selected as identity matrices.

Open your old version of Simulink model in the new version of Simulink software and do a save-as. Pay attention to any messages show up in the Command Window.
Or run slupdate(Model, 'OperatingMode', 'Analyze') to see what blocks need your special attention.
