一个ICA工具。This binary version of the runica() function of Makeig et al. contained

in the EEG/ICA Toolbox runs 12x faster than the Matlab version. It uses

the logistic infomax ICA algorithm of Bell and Sejnowski, with natural

gradient and extended ICA extensions. It was programmed for unsupervised

usage by Scott Makeig at CNL, Salk Institute, La Jolla CA. Sigurd Enghoff

translated it into C++ code and compiled it for multiple platforms. J-R

Duann has improved the PCA dimension-reduction and has compiled the

linux and free_bsd versions.
