Mar 09, 2015 · Euler’s Method in MATLAB: %function t=t(n,t0,t1,y0) function y=y(n,t0,t1,y0) h=(t1-t0)/n; t(1)=t0; y(1)=y0; for i=1:n t(i+1)=t(i)+h; y(i+1)=y(i)+h*ex(t(i),y(i)); end; V=[t',y'] plot(t,y) title(' Euler Method')

Dec 15, 2018 · The "Modified" Euler's Method is usually referring to the 2nd order scheme where you average the current and next step derivative in order to predict the next point. E.g., 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.
