Laplace transform of Poisson-Nernst-Planck with and solve with Bvp4c. I'm voting to close this question as off-topic because probably something is wrong with your equations, but this is not a programming question, so off-topic for SO. Matlab Laplace Transform of Square Wave. Sep 20,  · An inexact-Newton method will be used to solve the nonlinear differential equations. Since the Poisson-Nernst-Planck equations can be derived from the first variations of a free energy functional, the Newton-like methods can produce a convergent solution that corresponds to the minimization of the free vsync.pw by: Jun 05,  · How to solve Nernst Planck equation in Matlab.
