This video covers the polarplot command in Matlab. All the code shown works almost perfectly in Octave. In Octave, the command is simply "polar" rather than "polarplot." Also, some of the formatting does not work in Octave.
This video is part of a series comprising a complete introductory course in Matlab / Octave.
