boost

This example shows the use of the FFT function for spectral analysis. A common use of FFT s is to find the frequency components of a signal buried in a noisy time domain signal.

A new method for analysing nonlinear and non-stationary data has been developed. The key part of the method is the `empirical mode decomposition method with which any complicated data set can be decomposed into a nite and often small number of `intrinsic mode functions that admit well-behaved Hilbert transforms. This decomposition method is adaptive, and, therefore, highly ecient.
