I'm trying to program a system of two partial differential equations and I'm a little stuck on programming the boundary conditions. My boundary conditions are simply that the flux term should vanish, but from the documentation it's not clear whether pdepe requires two or one condition. The documentation states the following equation but without stating dimensions:

Got it! Thanks. Just one more question: does that mean I should also program c as a vector instead of a diagonal matrix? This is not the clearest part in the documentation. You really have to go through the examples to understand the syntax. Would be much clearer if they'd use the componentwise operation in the description of the formulas.
