Iterative Fourier Transform Algorithm

Hi does anybody have a working MATLAB code for Iterative Fourier Transform Algorithm (IFTA) for design of beam splitting diffractive elements. I need it urgently. Thanks in advance for help

Gerchberg-Saxton is pretty trivial to code. See the pseudo-code at <http://en.wikipedia.org/wiki/Gerchberg%E2%80%93Saxton_algorithm> for a start. It's all of about 10 lines. A good Fourier optics book like Goodman's will provide information on how to include parameters such as focal length and wavelength.

It gives bad title in searching this wikipedia link

Sorry about that:

The only place at this site that you might find it is the File Exchange.
