contains the following:

* The acdc algorithm for finding the

approximate general (non-orthogonal)

joint diagonalizer (in the direct Least Squares sense) of a set of Hermitian matrices.

[acdc.m]



* The acdc algorithm for finding the

same for a set of Symmetric matrices.

[acdc_sym.m](note that for real-valued matrices the Hermitian and Symmetric cases are similar however, in such cases the Hermitian version

[acdc.m], rather than the Symmetric version[acdc_sym] is preferable.

* A function that finds an initial guess

for acdc by applying hard-whitening

followed by Cardoso s orthogonal joint

diagonalizer. Note that acdc may also

be called without an initial guess,

in which case the initial guess is set by default to the identity matrix.

The m-file includes the joint_diag

function (by Cardoso) for performing

the orthogonal part.
