%description
Different algorithms to perform approximate joint diagonalization of a
finite set of square matrices. Depending on the algorithm, orthogonal or
non-orthogonal diagonalizer is found. These algorithms are particularly
useful in the context of blind source separation. Original publications of
the algorithms can be found in Ziehe et al. (2004), Pham and Cardoso
(2001) <doi:10.1109/78.942614>, Souloumiac (2009)
<doi:10.1109/TSP.2009.2016997>, Vollgraff and Obermayer
<doi:10.1109/TSP.2006.877673>. An example of application in the context of
Brain-Computer Interfaces EEG denoising can be found in Gouy-Pailler et al
(2010) <doi:10.1109/TBME.2009.2032162>.
