My apologies for the late reply, you can only run the CSVM model in older releases of Matalb. The documentation mentions matlab 2015b and earlier. The model relies on simdriveline first generation, which has been deprecated by Mathworks from version 2016a and later. We have not upgraded to newer generations of simdriveline as it is lacking in performance compared to the one we are using. If you really want to use matlab 2019b you could try and implement your own driveline.
