I am Connell D'Souza and I work at the MathWorks as the technical lead and the point of contact for RoboNation competitions. As part of our efforts to support teams taking part in RoboSub, we offer complimentary MATLAB and Simulink with 65+ products that can help you use MATLAB and Simulink as an end to end solution for your sub.
We are working on a video podcast channel called the MATLAB and Simulink Robotics Arena where we try and cover topics that are relevant to the community. I recently did a video with Stephen Cronin from the RAER on identifying the direction of arrival of an acoustic ping. You can find the video here : https://www.mathworks.com/videos/matlab-and-simulink-robotics-arena-direction-of-arrival-with-matlab-1504107605701.html?s_tid=srchtitle
Stephen was kind enough to share the code that he used to help get you started on MATLAB Central's File Exchange. I would be happy to hear from you about topics that you would like to us to create content on.
