According to some information, Kubios HRV already contains the necessary files to run properly. It does not need the full version of MatLAB because it contains the libraries and scripts to run as a standalone application. This is even mentioned on some documentation pages.
KUBIOS-HRV is available for Windows and Linux. It is a standalone MatLAB application (only the MatLAB runtime compiler and libraries, both included in the package, are needed in order to use it).
