Create two vectors, a and $b,$ with values ranging from $-10$ to $10$ at increments of $1.$ Use the meshgrid function to map a and $b$ onto two new two$-$dimensional matrices, $x$ and $Y.$ Use the matrices $x$ and $Y$ to calculate $Z$ using the equation:

$Z=sin(x)**cos(Y)+0\mathrm{.}1**(x^2+Y^2)$

Use the mesh and surf plot functions to generate two three$-$dimensional plots of Z$.$ Ensure that both plots resemble the given mesh plot.
