## Summary

Description

A three-dimensional surface plot of the unnormalized sinc function — precisely,

{\displaystyle {\begin{aligned}&-10\leq x\leq 10\\&-10\leq y\leq 10\\&z=\operatorname {sinc} \left({\sqrt {x^{2}+y^{2}}}\right)\\\end{aligned}}}

[X,Y] = meshgrid(-10:0.25:10,-10:0.25:10);
f = sinc(sqrt((X/pi).^2+(Y/pi).^2));
h = figure(1);
