阻尼系数的非线性估计：主要引入动态噪声，提高阻尼因子的可观察性(This implementation adds dynamic process noise(plant noise) to improve observability of thedamping factor.)

复杂网络相似性指标的实现和对比，同时可以实现无标度网络和邻耦网络两个复杂网络的预测。并对预测结果进行评估。改进了预测算法，提出了预测精度评价的新指标，使精度评价更准确。(Implementation and comparison of the complex network of similar indicators, and can achieve scale-free network and neighbor coupled network prediction of two complex networks. The prediction results to assess. Improve the prediction algorithm, proposed a new indicator of prediction accuracy evaluation, the accuracy of evaluation is more accurate.)
