Problem $23$: Use MATLAB to solve the following:

Consider the cable profile of a small suspension bridge carrying a uniformly distributed load:

The differential equation for this system is:

$\frac{d^{2}w}{d{x}^2}=1\mathrm{.}0$

Solve the above differential equation given the following initial conditions:

$w(0)=10$ and $w^{}(0)=20$
