matlab编写结构计算振型分解法，能求解多自由度问题，自动绘出振型(the preparation of structural calculations matlab vibration mode decomposition method to solve the problem of multi-degree of freedom, automatic mapping mode shape)

A simple minimizer of in-line coded functions, for teaching and experimentation

开关磁阻电机的仿真模型，主要涉及是电流斩波控制，里面模型是MATLAB自带(a simulation model of switched reluctance motor，mainly about current chopping control)

character recognition by a neural network, implementation done on matlab

采用数据拟合法进行的高斯白噪声信道下的信噪比估计，程序中有经典summer法以及本人自己拟合的二阶和三阶参数，适用于不同的信噪比范围，望大家一起交流(By data fitting of the Gauss white noise channel SNR estimation, the program in the classic summer method as well as my own fitting of the two order and three order parameters, applicable to different SNR range, hope everybody exchanges together)

说明：  使用matlab编写的BP神经网络的算法，使用单隐层的网络，其中包括一个实例文件，对20个数据作分类。(Prepared using matlab algorithm BP neural network, using a single hidden layer networks, including an instance of the file, the data for 20 categories.)

用FFT计算信号的功率谱密度时，需要先计算FFT，再计算双边谱密度，然后计算单边谱密度。在matlab里注意FFt要除以采样点数，计算双边谱时要注意除以频率分辨率。 ( When calculated using the FFT power spectrum density signal, you need to calculate the FFT, and then calculate the bilateral spectral density, and then calculate the unilateral spectral density. In matlab in Note FFt divided by sampling points should be noted when calculating the bilateral spectrum divided by the frequency resolution.)

AES 加密和解密的 MATLAB GUI 程序Demo 密匙长度 128、192、256bit 全部程序为源码设计(AES 128bit/192bit/256bit Demo )

生成纵横向四阶方程，计算特征根，传递函数等，给出波特图及尼科尔斯图。( SURVEY is set up to make calculations based on the 12 x 12 Fmodel and 12 x 7 Gmodel produced by FLIGHT, with the generic business jet model trimmed for flight at V = 102 m/s and h = 3,050 m. The flags are set to generate a fourth-order, body-axis, lateral-directional model the data set to calculate eigenvalues, eigenvectors, and the transfer function aileron to roll rate and to show the Bode plot, Nyquist plot, and Nichols chart for the transfer function.)

平稳随机信号谱估计 使用两种谱估计方法将信号和噪声分离：周期图法谱估计和Levinson-Durbin递推法谱估计。其中每种方法又细分为自编程序和使用matlab自带函数两种。( Random signal model is estimated using two methods of spectrum signal and noise separation: periodogram spectral estimation method and Levinson-Durbin recursive spectrum estimation method. Each method which is divided into self-fine procedures and the use of two matlab own function.)
