WebSelect Solution Mesh. Before solving the equation you need to specify the mesh points (t, x) at which you want pdepe to evaluate the solution. Specify the points as vectors t and x.The vectors t and x play different roles in the solver. In particular, the cost and accuracy of the solution depend strongly on the length of the vector x.However, the computation is much … WebIn 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; end In this case pdefun defines the equation ∂ u ∂ t = ∂ 2 u ∂ x 2. If there are multiple equations, then c , f, and s are vectors with each element corresponding to one equation. Initial Conditions
