function fasticag(mixedsig, InitialGuess)
%FASTICAG - Fast Independent Component Analysis, the Graphical User Interface
%
% FASTICAG gives a graphical user interface for performing independent
% component analysis by the FastICA package. No arguments are
% necessary in the function call.
%
% Optional arguments can be given in the form:
% FASTICAG(mixedsig, initialGuess) where the matrix mixedsig contains the
% multidimensional signals as row vectors, and initialGuess gives the
% initial value for the mixing matrix used in the algorithm.
%
% FASTICA uses the fixed-point algorithm developed by Aapo Hyvarinen,
% see http://www.cis.hut.fi/projects/ica/fastica/. The Matlab package was
% programmed by Jarmo Hurri, Hugo Gavert, Jaakko Sarela, and Aapo
% Hyvarinen.
