Chapter 10, Problem 20P

The geometry of a ship hull (Wigleyhull) can be modeled by the equation:

$y=\pm \frac{B}{2}\left[1-{\left(\frac{2x}{L}\right)}^2\right]\left[1-{\left(\frac{2z}{T}\right)}^2\right]$

where x, and z are the length, width, and height, respectively. Use MATLAB to make a 3-D figure of the hull as shown. Use B = 1.2,

L=4, T=0.5, $-2\le x\le 2$ and $-0.5\le z\le 0$ .
