Solve the following differential equation using the first$-$order Euler method.

$\frac{y^{\text{'}}}{y}=-\frac{1}{2},y(0)=5,$xin$[0,10]$

Also write in the same script:

:Plot the solution by Euler as $*$

Also plot the analytical solution $y=5e^{-0\mathrm{.}5x}($This question$/$problem must be solved using MATLAB coding, pls provide the answer as MATLAB code$)$
