hibert变换程序

file "README.TXT"

The package includes the main Matlab program DECOMP for non-stationary
and nonlinear vibration signal decomposition together with the program
PL.M for plotting the obtained decomposed results. It also includes some
simulation examples and the demo program RUN (Matlab 7.x). 
The Hilbert Vibration Decomposition method is based on the Hilbert transform 
signal processing [*]. Run the program RUN and choose a vibration signal. 
Press the button 'RUN' to start the decomposition procedure.

Function DECOMP (Hilbert Vibration Decomposition) 

The function DECOMP is a signal processing M-File (Matlab 7.x).
It extracts intrinsic quasi-harmonic components Y(t) from the initial
signal composition y(t). 

[Y,A,F,dev]=decomp(y,2);
