I need help to do this problem please because i don't understand how does it work!
I did these steps on matlab,
x= -5:1:5;
y= -5:1:5;
r= sqrt(x.^2 +y.^2);

The sinc function is very important in digital signal processing as it is the Fourier transform of a rectangular pulse and is used extensively in interpolation. The sinc function is given by: sinc(t)= sin(π t)/(π t) when t ≠0 sinc(t)=1 when t=0 We will graph the sinc function in 3D to understand better its shape. Write a script that creates a plaid of x and y values that vary between -5 to 5. Choose an adequate step size. Calculate r which is given by: r= √(x^2+ y^2 ) Then, plot using x, y, and sinc(r) using a mesh plot. You can either write your own function for sinc or use MATLAB’s built in function. Include your code and plot below. Skills – 3D mesh plots in MATLAB, meshgrid.
