Speech analysis in matlab

This is the presentation explaining implementation of DES algorithm.

您好： 这个matlab程序是用周期循环检测算法检测：首先运行a.m程序，通过此程序运算得出循环频率a值；再运行zhouqi.m程序，对a值进行确定，通过周期循环算法对信号进行检测； (Hello: This procedure is used matlab cycle detection algorithm: First run a.m program, obtained through the operation of this procedure cyclic frequency of a value to run zhouqi.m procedures, a value determined by the signal cycle algorithm detection )

岭回归程序 输入参数为自变量、因变量和优化因子 输出参数为映射矩阵与回归误差(Ridge Regression. Input parameters: - X: Input data block (k x n) - Y: Output data block (k x m) - q: Stabiliaztion factor (optional) If not given, estimated from data Return parameters: - F: Mapping matrix, Yhat = X*F - error: Prediction errors)

掌纹识别的matlab程序，包括最大内切圆求法，KL变换，小波变换，欧式距离识别方法(Palmprint recognition matlab program, including the largest inscribed circle Method, KL transform, wavelet transform, Euclidean distance to identify methods)

KNN, K最邻近算法 交叉验证，选出KNN算法中较优的K值(KNN：K nearest neighbours cross validation, for the choice of the best K in KNN algorithm)

运用随机森林方法对数据进行建模，可以用模型进行预测与分类(Random forest prediction and classification)
