enigmae has asked for the wisdom of the Perl Monks concerning the following question:

When using the MATLAB software in college for signal analysis we did FFT's on raster images using two-dimensional FFT's for edge detection and finding patterns in the image. This was one of the coolest and slickest uses for FFT's on image analysis however i was disappointed not to find an FFT module that can do these on multi-dimensional arrays. Using MATLAB is one thing, but programming these from ground up seems like a daunting but challenging task. Before I go off and reinvent the wheel I wanted to ask if anyone has done or seen some work done in perl using FFT's with multi-dimensional arrays?
Thanks for your time,
