WebAfter you solve an equation with pdepe, MATLAB returns the solution as a 3-D array sol, where sol(i,j,k) contains the kth component of the solution evaluated at t(i) and x(j). In general, you can extract the k th solution component with the command u = sol(:,:,k) . WebThe software determines the initial absolute tolerance based on the value of the relative tolerance. abstol = reltol * 1e-3 when reltol ≤ 1e-3. abstol = 1e-6 when reltol > 1e-3, where abstol is the absolute tolerance and reltol is the relative tolerance. As the simulation progresses, the absolute tolerance for each state is scaled to the ...
