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);

Your introductory question got truncated. You should only put a brief summary of the question in the title and post all of the important parts in the body of the Question.

With the missing part of the Question, the work you have done so far does not appear to have any relevance to the question.

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.

that's the question.
