Wavelet examples

The software and example data in the wave_matlab directory are borrowed directly from the wavelet website of Christopher Torrence and Gilbert Compo. See references below. I have made (and documented) minor modifications to chisquare_inv.m so that it works with GNU Octave. It might still work with Matlab.

The programs_cck directory contains a nice example of wavelet filtering.

An example using real observational data is in the LIGO directory.

Some useful references

For inspiration, the GW discovery paper.

Excellent wavelet introduction by Torrence and Compo.

The importance in understanding the noise power spectrum in data, how it may be modified by digital filtering, and how to take all this into account when using the Torrence and Compo wavelet software.
