CubICA ver. 2003-05-19

CubICA performes ICA by diagonalization of third- and
fourth-order cumulants simultaneously.

for details on the algorithm see:
   Blaschke, T. and Wiskott, L. (2003).

=================================
Installation and Starting Demo:
=================================

- download source from http://itb.biologie.hu-berlin.de/~blaschke/matlab/
- uncompress and untar source:          
	tar xzvf cubica.tgz

- start matlab
- cd /yourinstallationpath/cubica/
- type cubica_demo

====================

The package includes:

cubica34.m     core ICA-function for skew and symmetrically distributed source signals
cubica34a.m    approximated version of cubica34 
cubica4.m      ICA-function for symmetrically distributed source signals
cubica4a.m     approximated version of cubica4

sir.m          function to evaluate unmixing performance
	       (good performacne->small outputvalue)
