I want to solve in matlab an ODE of second order for a problem of thermal diffusion, I need to set my temperrrature as boundary conditions at x=0 and at x=0,5 (or T'=0 at x=0,25).
How can I set my code?
I try to use ode45 but the problem is the initial conditions request are only for x=0.
this is my code
funz=@(x,T) [T(2); -sigma0*(1-b*(T(1)-Tw))/k];
tspan=[0 s];
y0=[Tw ????]

This is a boundary value problem, not an initial value problem.
Thus you should use bvp4c instead of ode45.
