How to create an image based on mathematical equation?

Hi,

I need to obtain an image from the following mathematical equation. As I am new at MATLAB, I would really appreciate your help.

The equation is shown in the attached image.

rows = 480; % Whatever you want.
columns = 640;
I = ones(rows, columns);
I(:, columns/2) = 0;
imshow(I, []);

x=0 is in the middle of the image, at column 319.5

As I have to find afterwards the Point Spread Function of the image, do you think it is a correct to do it this way? I also generated a solution similar to yours, but I was wondering how can I apply the 2D Coordinate System and plotting the image. Thank you very much for your help!

There is no point spread function for that image. An image, half black and half white, is not an imaging system. Nor was it produced by one, so there is no PSF.

I uploaded a copy of the problem of my assignment. Could you please check it then, and tell me how can I approach it? Because as I understood, I'd have to find the PSF of the image.. Thanks in advance!

The edge response is related to the PSF. You should have gone over that in class. See this for some background http://www.dspguide.com/ch25/1.htm or google it.
