I am trying to solve the following PDE (one-dimension diffusion): with the following boundary condition : I read the documentation here :http://www.mathworks.com/help/matlab/math/partial-differential-equations.html?refresh=true#f1-697925and I saw that it works for...
hi, all I am trying to use coefficient from PDE to solve helmholtz type partial differential equation. (I know there is helmholtz equation, but both module doesn't working) So, first I am using COMSOL 4.4 with MATLAB, and I follow the instruction as following link to use MATLAB ...
Written in this form, you can read off the values of the coefficients c, f, and s. In MATLAB you can code the equations with a function of the form function [c,f,s] = pdefun(x,t,u,dudx) c = 1; f = dudx; s = 0; endIn this case pdefun defines the equation ∂u∂t...
I am not an expert in MATLAB and I did my best in coding my 5 PDE's using pdepe command but keep getting this massage? Z must be a matrix, not a scalar or vector. My codes are ThemeCopy m = 0; x = linspace(-10,20,200); ...
