数学建模，优化计算，以及模型实例， funtool - 函数计算器 tutdemo - MATLAB优化教程 mathmodl - 工具箱演示 (Modeling)

适合初学者使用的非常清晰的人脸识别PCA算法，可运行成功。( a simple program, very useful!)

my experiments which are very useful

说明：  利用matllet算法的小波消噪程序 噪音区间可以自定义(Matllet algorithm using wavelet denoising process noise interval can customize)

基于焊接图片的pca降维，knn分类算法。(Pca-based solder image dimension reduction, knn classification algorithm.)

用Arnold方法对图像进行置乱，目的使图像随机分布均匀(Arnold method using the image scrambling, the purpose of uniform random distribution of the image)

说明：  最小二乘法拟合曲线（用到矩阵求逆、矩阵乘法、矩阵转置）(Least square fitting curve (use matrix inversion, matrix multiplication, matrix transpose))

AR预测模型算法实例，针对现在数据对未来数据进行预测，程序中给出油价实例非常实用！(AR prediction model algorithm examples, now for the future for data prediction, very useful!! )

implementation of butterworth high pass filter

说明：  这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)
