I just downloaded the current version of Panthera Free and I am unable to run Simulink blocks To/From Panthera because of missing library vehicleLib (this dependency is in the block 'from Panthera') and
also because some mex64 files are missing (most importantly udpin/out).
I have previously used some older version which was working without problems.
To reproduce: - install Panthera free - run m_install.m in Matlab - import 'from Panthera' and/or 'toPanthera' blocks to Simulink - try to run the model
Thanks for downloading Panthera Free, unfortunately I am not able to reproduce the issues you are having. What I can say however, is you need to make sure that <Install_directory>\ePhysNet\blocks_x64 or blocks_x86 (depending on the system architecture) is in the Environment Path of your MATLAB.
You can type in "path" in the Matlab command window to double check. And also make sure that "vehicleLib.mdl" is located in the path, for simplicity it is included in the same map as your vehicle model. Hopefully these tips will help resolve the issues you are having. If this is not the case could you send a few screenshots? Also which release of MATLAB are you using?
