Hi everyone!
I have to solve **THIS** system of coupled nonlinear PDEs with **THESE** boundary conditions in one dimensional case (domain: [-L,L]). This is a boundary value problem (BVP). There, *t* is the time-variable whereas *u* is the space-variable. The functions **gamma**, **beta** and **tau** are nonlinear in *lambda* (which is function of *u*) through power law (prop to *lambda*^-2).
How can I solve it using Matlab?

Thanks, Petrus

Doesn't look like a BVP to me

the boundary conditions are declared at the boundary of the domain [-L,L], where each function has to have zero-first derivative. Why does not like as BVP to you?
