FrtDemo.m :

Function FrtDemo
FrtDemo by itself, opens a demonstration GUI for manipulating
the fractional Fourier Transform, allowing to choose between
different signals (multichirp paralel or in triangle, rectangle window)

FrtDemo(signal)
Open the GUI with an input vector signal and allows to perform different operations such as sweeping various fractional order and raw filtering (zeroing) in fractional domains.
Signals can be represented in time waveform or spectrogram.

FrtDemo should be self sufficient, it only
requieres signal processing toolbox for spectrograms plot.

See help include for further details.

Other m functions of the package :

The other functions implement separately what the Demo does.
Function frtfilm.m creates avi file from the evolution of the FRT for
various angles. (requieres an avi export function, avalaible with matlab 6.0
or in the matlab central resource). filmporte.m shows an example of how it works.
Function frt_nopad.m implements the fractional transform, without padding the signal.
Function frt.m implements the fractional transform, pads the signal to a dyadic length.

CodDemo.m :

Function CodDemo
CodDemo by itself, opens a demonstration GUI for manipulating a transform coder scheme, allowing to choose between different strategies.

Sorry this version doesn't seem to work correctly under windows platforms. Changes should be not so important, and the windows version should soon be available.

See help include for further details.

Other m functions of the package :

The other functions are necessary to CodDemo. They implement separately the
different solutions.
