GNU Octave uses the Matlab language, though not all the libraries that are available for Matlab are avaialble for GNU Octave. This does not prevent you from coding these functions up yourself. The GNU Octave team has a reporting method that allows you to report if a function does not work the same as it does in Matlab.
GNU Octave is also uses the interpreted method. Both Python and C# are interpreted, but I am not sure about R. I know of it, but I have not used it.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
