Given the following differential equation: $f=4^{**}$exp$(0\mathrm{.}8**x)-{0\mathrm{.}5}^{**}y,$ where initial point $a=0$; finish point $b=3$; initial condition $y_0=y(x_0)=2,$ step $h=0\mathrm{.}2.$

Using the Modified Euler's method find the numerical solution for value y$(2)$ using MATLAB $.$

Remark: MATLAB script file in Module $9,$ Problem $2$ "Mod$9\_$Modif$\_$Euler$\_$examples" can be used.
