Hi,
I am looking forward to help you with this project. I have access to Matlab and I have recently worked in a Matlab project (outside Freelancer.com). It was about the numerical solution for a modeling problem, using 4th order Runge-Kutta method . Feel free to take a look on my portofolio.
I will be waiting for your contact and I would also appreciate knowing more details about your requirements.
Best regards,
Vinícius.
