E.g., Theme. Copy. dy1 = dy (x,y); % derivative at this time point. dy2 = dy (x+h,y+h*dy1); % derivative at next time point from the normal Euler prediction. WitrynaImproved Euler method can be split into two equation, but it should rather be called two steps. You basically perform one Euler step, but this time you call the solution y n + 1 ∗. You then use the average of the slope at y n and y n + 1 ∗ to approximate the slope for your step y n + 1 = y n + h ⋅ s with s = ( f ( y n) + f ( y n + 1 ∗ ... small stickers aesthetic
