I ran my simulink model in different versions of Matlab, 2007, 2009, 2011, 2012, 2014. All gave different results. Which is the most accurate one, and why?

Hi Mehmed,

in this generality it's not possible to answer. How big are the differences? Note, that a simulation always is subject to numerical differences in the order of floating point accuracy. If the model you are simulating is unstable, errors might pile up. Please give some more details, maybe some help regarding modeling is possible.
