tca_statio.m

The tca package is a Matlab program that implements the tree-dependent component analysis (TCA) alg

function [W,tree]=tca_statio(x);
% CLUSTER_TCA - Tree-dependent Component Analysis of stationary time series
%               with default options
%
% for a function with options, seee tca_options.m

n=size(x,2);
