Email: feel free to contact me regarding my shared files on the file exchange. I don't do free consulting outside of the forum so if you have a Matlab question, post the question to the forum and you may email me the link to the question.

About me: Finishing PhD soon on topics related to vision science; neurophysiology; sensory-motor feedback and control; control systems; steering & navigation; multisensory integration; top-down bottom-up feedback loop.
