in Matlab Write an algorithm. This algorithm includes the methods of euler method, heun's method and runge kutta (4 order). It will also contain error analysis and this will give the result as a table and give the calculation of the orders graphically. Also, each method used will appear on another chart with the exact solution. . y=((t^2)-y), yexact=t^2-2*t-exp(-t)+2 y(0)=1
