With regard to the pdepe-tutorial on the mathworks page the first column vector on the left equals the 'c-Term', the first matrix on the right equals the 'f-term' and the second matrix on the right equals the 's-term'. Partial Di?erential Equations in MATLAB 7.0 P. Howard Spring 2010 Contents The command pdepe will combine these M-?les and return a solution to the MATLAB M-?le that takes values of x and returns values ?u(x). Observe in this M-?le that When you made the change, the flux went down by a factor of 1/pi^2. That's fine, but one of your boundary conditions depends on the flux and you need to change that one to compensate. Taken from the Matlab 2016b documentation for pdepe: . The time integration is done with ode15s. pdepe exploits the capabilities of ode15s for solving the differential-algebraic equations that arise when Equation 1-3 contains elliptic equations, and for handling Jacobians with a specified sparsity pattern. matlab pdepe boundary conditions help.

We explore the PDE Toolbox for MATLAB 7.10.0. The speakers, in order of appearance, are Iain Crosby, Taha For the boundary condition I've set the left (pl) to a constant value of 280 with the idea being that this value will always be 280, however when i output the results the value is instead 4e10 and appears to be changing. I'm trying to solve a partial differential equation of the type that can be solved with pdepe. I based my code on the one I found in the Help. The only trick of my code is that one of the boundary conditions contains a time-dependent parameter that has to be numer
