Hello there. I'm interested in your project and would like to offer you my help. I've been using Matlab for more than two years and have gotten a lot of experience making codes to aid me during my career (Aerospace Engineering). I specialize in GUI's and numerical methods, but I can do most stuff. I have completed courses too, the latest called "Advanced Matlab for Scientific Computing" by Stanford Online.
I've read the paper and it doesn't seem that complicated, I could make you a code in Matlab with no problem. I would only need the data to make the plots of course.
Let me know if you're interested, thank you!
