matlab时频分析配套源码第3章的程序，请大家共享(Matlab time-frequency analysis supporting source Chapter 3, please share)

以mathematica9中文版来计算由牛顿迭代法产生的实根。因开发环境中没有mathematica,故只好选matlab.(Using mathematica9 to calculate the real root produced by the Newton iterative method. The station is estimated without.)

快速经验模态分解程序包，能够实现时间序列数据的模态分解(The fast empirical mode decomposition package can realize the modal decomposition of time series data)

此为牛顿与拉格朗日插值算法的matlab程序，参照数值分析教程的公式编写，确定可用。(This is Newton and Lagrange interpolation algorithm matlab program, refer to numerical analysis tutorial to prepare the formula to determine the available.)

Bouc-Wen非线性滞回模型仿真程序，通过此程序可观察Bouc-Wen模型中各参数对其所描述的滞回曲线形状的影响(Bouc-Wen nonlinear hysteretic model simulation program, described by the Bouc-Wen model parameters on the hysteresis curve shape can be observed through this program)

能够运用最小二乘发计算频谱，可以精确估算频谱(good way)

用SDP方法计算基于方差的客观不确定性指标的程序。(Calculated using the SDP uncertainty variance based on objective indicators of the program.)

说明：  对数值进行分析，AP聚类算法是基于数据点间的"信息传递"的一种聚类算法。与k-均值算法或k中心点算法不同，AP算法不需要在运行算法之前确定聚类的个数。AP算法寻找的"examplars"即聚类中心点是数据集合中实际存在的点，作为每类的代表(For numerical analysis, AP clustering algorithm is based on the "information transfer" between data points. Unlike k-means algorithm or k-center algorithm, AP algorithm does not need to determine the number of clusters before running the algorithm. The "examples" searched by AP algorithm is the actual points in the data set as the representative of each class)
