Real-World Problems

Average Problem Difficulty:

There are some great problems on Cody, but many of them are rather theoretical.
Being an engineer, I want to use MATLAB to solve practical challenges, so here I have grouped together some problems - some easy, others less so - based on real-world questions (including a few of my own!).
