The method follows directly from the definition of the largest Lyapunov exponent and is accurate because it takes advantage of all the available data. In both cases there is extensive documentation and sample input files. Acta Acustica united with Acustica, Hirzel Verlag, 2000, 86 (3), pp.557-567. For delay systems the sign of the sub-Lyapunov exponent (sub-LE) determines key dynamical properties. The local Lyapunov spectrum is calculated as follows: 1 A delayed embedding of the input time series is formed. The invention provides a method for determining the maximal Lyapunov exponent of a chaotic system. Hegger R, Kantz H. Improved false nearest neighbor method to detect determinism in time series.
