说明：  平均周期图法和平滑平均周期图法估计功率谱 从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!! 用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)

power_VariableInductor,matlab仿真文件,电力电子、功率电子控制方面很有价值，调试通过(aspects of power_VariableInductor, matlab simulation files, power electronics, power electronics control valuable debugging through)

要用灰色模型预测2020年人口数，请赐教(In the gray prediction model to the population in 2020 ..)

一款比较新的绘图软件的电脑书籍，比MATLAB更容易实现(A relatively new mapping software to computer books, is more easily achieved than in MATLAB)

说明：  hopfield神经网络实现：（1）两个三维的稳定点，（2）从大小为12*10的黑白图像识别数字(hopfield neural networks: (1) the stability of two dimensional points, (2) from the size of 12* 10 black and white digital image recognition)

与上一个相对应，这是相反的过程，用于小波重构，多重小波重构(with a correspondingly, and this is contrary to the process used wavelet reconstruction multiwavelet Reconstruction)

这个还不错，对自己的matlab水平会有明显的提高(great)

plot figure no focus(figure no focus)

rainbow option.m in the matlab to compute the value of bariier option (to compute the rainbow option an others)

说明：  利用ARMA、AR、MA模型，以及周期图等进行系统参数估计(use ARMA, AR, MA model and cycle map for parameter estimation system)
