how i can plot this 3D graph ?

Create a plot of the sinc® function shown in a previous slide, but in this case make the plot region a circular area in the xy plane that has a radius of 3p. (Hint: you will need to create an xy plaid but computed from a grid defined using polar coordinates.) Add a circular disk of radius = 3p to the above sinc® plot. (Hint: you can use hold on to add additional surfaces using the surf command just like you did for plot() ). Now add a vertical plane (y=0) and a second vertical plane (x=0) to the plot. This effectively partitions the surface into 8 regions. <<<http://mathworks.com/matlabcentral/images/surf.gif>>>
