Need help with matlab problem.

Consider again the Van der Pol equation:

$\frac{d^{2}y}{d{t}^2}-(1-y^2)\frac{dy}{dt}+y=0$

But this time formulated as a boundary value problem with $y(0)=0$ and $y(4)=1.$ Take $=0\mathrm{.}5.$

Note:

Create a local function for the Van der Pol equation with $=0\mathrm{.}5.$ Check correct syntax for referencing it in ode$45.$

Creare the residual function as a local soltuion and formulate the boundary conditions as a roots problem using fzero. Check correct syntax for referecing the residual function in fzero.
