I have not studied fractional Fourier Transforms but it looks like the concept may help other types of processing.  It looks intriguing. 

I found this file (fpft.m) at: 

http://www.mathworks.cn/matlabcentral/fileexchange/9200-partial-fast-fourier-transform?controller=file_infos&download=true

which also has a link to a descriptive .pdf file at: 

http://crd.lbl.gov/~dhbailey/dhbpapers/   (#16 and 17 or search "fractional fourier")

The paper explains the fractional FFT and applications.  The matlab script uses it in a fast partial FFT algorithm.  What is your application?
