Hi Marco,
I understand that the following code
>> h = tf([1 2 3],[4 3 5]); [R,K] = rlocus(h);
is giving you error in R2017a.
I was not able to reproduce this on my end in R2017a. Given the fact that the error points to a missing DLL file, your best bet would be to reinstall MATLAB and run the code again upon re-installation.
Hope this helps.
Thanks,
David
