一个好用的信号特征提取、信号消噪代码

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)

契比雪夫数字滤波器对心电信号进行数字滤波，采用零相位数字滤波，比较好的去处了基线漂移，比较适合于ST段的检测(the source program is about digital filter of Ecg signal ，we design a Chebyshev digital filter，we are satisfied about the results， succeeding in removing the baseline driftso be glad to share with you，)

包含cometexample,diamondplot3,pieexample,等绘图函数的源代码，以及关于涉及到的绘图函数的介绍，很有价值！！！！(The source code that contains the cometexample, diamondplot3, pieexample, and other drawing functions, as well as on the drawing functions involved, the great value! ! ! ! )

可以对一幅图像提取边缘直方图，很有用的，用与图像匹配(Can extract the edge of an image histogram, useful, and image matching using)

说明：  水果特征提取，非常好，有大量实物图片及代码(Feature extraction of fruit, very good, there are a lot of pictures and code-kind)
