首先对采样信号进行傅里叶变换，计算出功率谱或幅值谱，然后用功率谱或者幅值谱的数据，计算每一个中心频率的带宽内数据的平均值。(Firstly, Fourier transform is applied to the sampled signal to calculate the power spectrum or amplitude spectrum, and then the average value of the data within the bandwidth of each center frequency is calculated by using the power spectrum or amplitude spectrum data.)

随机序列生产一维信号 用DB3小波进行二尺度分解 示范了dwt函数的用法 计算重构信号和原始信号的误差(Random sequence to produce one-dimensional signals DB3 wavelet decomposition of two-scale demonstrates the usage of computing functions dwt reconstructed error signal and the original signal)

关于IEEE-6、14 30节点系统很实用的，经过运行可靠MATLAB程序上的潮流计算(power flower)

网上流传的LLE原始代码无法运行的同学请看这里，这是我最新修改的代码，保证能在MATLAB2012上运行(Students circulated on the Internet can not run the original code LLE Look here, this is my latest revised code, guaranteed to run on MATLAB2012)

说明：  lda是一个集合概率模型，主要用于处理离散的数据集合，目前主要用在数据挖掘（dm）中的text mining和自然语言处理中，主要是用来降低维度的(lda is a set of probability models, mainly for dealing with discrete data sets, the key used in data mining (dm) in the text mining and natural language processing, is mainly used to reduce dimension)

清音和浊音的平均幅度，短时过零率，基音周期，对数幅度谱，高低时部分(Voiceless and voiced the average range, short-term zero crossing rate, pitch period, the number of amplitude spectrum, high or low section)

使用“改进的欧拉公式”和“4阶龙格-库塔公式”分别对Volterra方程求解，绘制解曲线、相轨线，并将结果进行比较。(Using the " improved Euler formula" and " 4-order Runge- Kutta formulas," respectively, Volterra equations, draw solution curves, phase trajectories, and the results were compared.)

大学时候跟导师做的一个暂态电磁场数据分析的程序，用于自动检测和识别波形数据中的脉冲起始时间等参数(University instructors often do with a transient electromagnetic field data analysis procedures, for the automatic detection and identification of waveform data pulse parameters, such as start-up time)
