write a complete Matlab code that plots the contour of the energy height and specific excess power in a height vs airspeed graph for this aircraft. All info is given in the image attached. Formulas:

$H_e=\frac{mgh+\frac{1}{2}m{V}_{}^2}{W}=\frac{mgh+\frac{1}{2}m{V}_{}^2}{mg}$

$CD=0\mathrm{.}035+0\mathrm{.}05(C{L}^{{?}^{{?}^{?}}}2)+CDW$

$P_s=\frac{d{H}_e}{dt}=\frac{dh}{dt}+\frac{V}{g}\frac{dV}{dt}$
