Yes, the horizontal vertical structures are to be expected. The stadium is convex and in a zeroth approximation just a rectangle. A rectangle shows the same horizontal vertical structures: dr = DiscretizeRegion[Rectangle[{-3/2, -1}, {3/2,...

High-order series solution of the ODE around x=0 followed by a Pade approximation. difference calculates the difference of the approximation to the right boundary value. It also returns the actual Pade approximation. ...

Here is an old piece of code from many years ago that does something similar: circlesOnCircles[?_, ?_, ?_, iter_] := Module[{C, ?, cp, \[ScriptD], ?, ?}, C[?[mp_, r_, {?_, ?_}, -1, i_]] := (cp = mp + r (\[ScriptD] = {Cos[?],...
You can also try this:[mcode]\[Rho]M[t_] = Table[\[Rho][i, j][t], {i, 2}, {j, 2}] H = PauliMatrix sol1 = DSolve[{I \[HBar] \[Rho]M'[t] == H.\[Rho]M[t] - \[Rho]M[t].H, \[Rho]M == Table[\[Rho]0[i, j], {i, 2}, {j, 2}]},...
