独立成份分析（ＩＣＡ）以及ｗｉｎｎｅｒ滤波 Source separation of complex signals with JADE. Jade performs `Source Separation in the following sense: X is an n x T data matrix assumed modelled as X = A S + N where o A is an unknown n x m matrix with full rank. o S is a m x T data matrix (source signals) with the properties a) for each t, the components of S(:,t) are statistically independent b) for each p, the S(p,:) is the realization of a zero-mean `source signal . c) At most one of these processes has a vanishing 4th-order cumulant. o N is a n x T matrix. It is a realization of a spatially white Gaussian noise, i.e. Cov(X) = sigma*eye(n) with unknown variance sigma. This is probably better than no modeling at all...( Source separation of complex signals with JADE.

matlab程序，对一个混沌系统进行仿真。 lyapunov.m是计算的主程序；qi_hyper.m是一个例子（qi系统），利用qi_hyper_lyap.m计算所有李氏指数，利用qi_hyper_lyapDim.m计算分形维数。其他系统稍作改正就可使用。经验证程序比其他计算李氏指数的更为有效精确。(matlab program for a simulation of chaotic systems. lyapunov.m are calculated in the main program qi_hyper.m are a case in point (qi system), the use of all qi_hyper_lyap.m calculated Lyapunov exponent, using qi_hyper_lyapDim.m calculated the fractal dimension. Other systems can be used to make some corrections. Experience in the certification process than any other computing Lyapunov exponent of the more effective precision.)
