Fast Iterative Filtering for the decompostion of non-stationary signals [1,2,3].

Please refer to "Example_v8.m" and "Example_real_life_v6.m" for examples of how to use the code.

It is based on FFT, which makes FIF to be really fast [2,3]. This implies that it is required a periodical extension at the boundaries.

To overcome this limitation we can preextend the signal under investigation [4]. We do it thanks to the function "Extend_sig_v2.m". See "Example_real_life_v6.m" for an example of application.
