Hey gang, how would you specifically define what a non-linear DE is? I mean, what specifically qualifies a DE to be nonlinear, and what does that mean? I am currently working with a team that models brain function as an array of coupled oscillators with complex feedback profiles and I understand the the DE's that are put in the Runge-Kutta solver are nonlinear, but looking at a symbolic equation on a chalkboard, I'm not sure if I could pick out a non-linear ODE from a linear one. Could someone help?(adsbygoogle = window.adsbygoogle || []).push({});
