HW$13$

$(50$ Points$)$ Create $x$ and $y$ vectors from $-5$ to $5$ with a spacing of $0\mathrm{.}5.$ Use the meshgrid function to map $x$ and $y$ onto two$-$dimensional matrix called $x$ and $Y.$ Use your new matrices to calculate vector $Z,$ with magnitude

$Z=sin(\sqrt[\phantom{2}]{x^2+y^2})$

a$)$ Use the mesh plotting function to create a three$-$dimensional plot of $Z.$

b$)$ Use the surf plotting function to create a three$-$dimensional plot of $Z.$use matlab codes please
