I have coupled pde-ode equations, where pde's one boundary condition is ode's input parameter. I want to write both equations as PDE so that I can use pdepe, but cannot figure out how to get boundary condition of pde and pass that to ode in pdefun. Could anyone tell me how to code it in order to use pdepe? Thanks!
for example, on x from 0 to 1, i have
dC1/dt = d^2 C1 / d x^2
dC2/dt = C2 - C1(x = 1)
pde's BC : dC1/dx = C1(x=1) - C2
