MATLAB code is required for Euler backward and trapezoidal to solve ODE for below equation:

Euler forward is as below

function v = f1(t,u) v=-150*u+49-150*t; end %actual function y=f(t,epsi) y=epsi*exp(-150*t)-t+1/3; end; epsi=0; eta = 1/3+epsi1;

function [t,u] = eulerforward(func,I,eta,n) h = (I(2)-I(1))/n; t= (I(1):h:I(2)); u(:,1) = eta; for i = 1:n; u(:,i+1) = u(:,i)+h*feval(func,t(i),u(:,i)); end end; err=norm(u-y,inf);
