I try to answer MATLAB-related questions on Code Review, but I don't have any fancy toolboxes, so I can't help with question containing code from the Neural Network toolbox etc.

I have constructed advanced fighter-jets, mind control devices, a weather control device, a teleportation device, robots, clones, a working Transporter device from Star Trek, time machines, a Multiverse Transporter, a shrinking pod, as well as an assortment of guns including lasers, rocket launchers, and crossbows.

I do this by combining MATLAB and skills I acquired while doing my MSc. in Electrical Engineering.
