1. a kind of recognition methods of the chaos time sequence based on Random Matrices Theory, it is characterised in that it is concretely comprised the following steps:

  • A, the time series of pre-identification is randomly selected, the selection range of the time series is Time sequence of noise and known chaosOne kind in the time series of system, and original matrix X is built according to the time series;

    B, matrix X is normalized, it is 0 to be translated into row vector average, and variance is 1 non-Hermite MatrixC, the non-Hermite Matrix that will be obtainedCalculate its singular value equivalent matrice Xu, then to singular value equivalent matrice XuThe matrix product of standard is calculatedD, according to the matrix product of standardIts characteristic value is calculated, and calculates the average spectral radius of characteristic value;

    E, according to the monocyclic law of Random Matrices Theory, it is Time sequence of noise or chaotic time sequence to identify the time seriesRow.
