WebGear's method, implemented in Matlab as ode15s and in SciPy as method='bdf' , is better (more stable) on stiff systems and faster on lower order systems than Runge Kutta 4-5. On higher order non ... WebJul 15, 2015 · RK4 will be exact if the solution is a polynomial of degree 4 or less. Initial "absolute maximum difference error" in RK4 method is equal (or) higher than Euler method for coarse grid and reduces with refining grid for problems with shorter waves relative to grid. Because convergence rate of RK4 method is more than Euler.
