Consider the below ODE:

$\frac{d^{2}y}{d{t}^2}-4\frac{dy}{dt}+\frac{y^3}{t}=12$

$y(0)=4$

$\frac{dy}{dt}(0)=-2$

In the textbox below, type two sets of Matlab codes $($clearly distinguish the two sets of code$)$:

$(1)$ a Matlab function that defines the ODE,

$(2)$ a Matlab script that solves the problem with ode$45$ for time $0t15,$ and then plots the solution.

For the toolbar, press ALT$+$F$10($PC$)$ or ALT$+$FN$+$F$10($Mac$).$
