The sinc function is very transform of a important in digital signal processing as it is the Fourier rectangular pulse and is used extensively in interpolation. The sinc function is given by: sinc(t) = sin(pi t)/pi t when t notequalto 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 = squareroot 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
