计算转子固有频率的传递矩阵法，包括prohl，ricatti等(Calculate the natural frequency of rotor transfer matrix method, including prohl, ricatti etc.)

决策树算法的CART算法，用MATLAB编写，能有，不错的。(CART decision tree algorithm algorithm, using MATLAB to prepare, to have, good.)

五点差分和九点差分和五点差分和九点差分五点差分和九点差分(Five points and nine pointsFive points and nine points)

som SOM 算法的 matlab 代码(MATLAT SOURCE CODE OF som ALGORITHM)

说明：  BP算法有详细的注释，数据归一化处理，数据打乱处理，功能强大(BP algorithm has detailed notes, normalization of data processing, data disturb processing, powerful)

本案例基于MATLAB的GUI工具进行设计仿真实验：通过对采集的车牌图像进行灰度变换、边缘检测、腐蚀及平滑等过程来进行车牌图像预处理，并由此得到一种基于车牌颜色纹理特征的车牌定位方法，实现车牌区域定位，最后实现车牌字符的分割与识别。(In this case based on MATLAB GUI design simulation tool: through the license plate image capture through gradation conversion, edge detection, corrosion and smoothing process for the license plate image preprocessing, and thereby obtain a color texture features based on license plate the method of license plate location, license plate positioning to achieve, and finally realize the segmentation and recognition of license plate characters.)

实用的matlab教程，个人感觉内容详细具体，对我帮助很大(Practical matlab tutorials, detailed and specific contents of personal feeling, helped me a lot)

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)
