这个是有关于语音识别的的书籍，上面有很多基本原理和MATLAB的例子(This is a reference book for automatic speech recognition with matlab codes.)

Matlab多种图像边缘检测方法 1、用Prewitt算子检测图像的边缘 2、用不同σ值的LoG算子检测图像的边缘 3、用Canny算子检测图像的边缘 4、图像的阈值分割 5、用水线阈值法分割图像 6、对矩阵进行四叉树分解 7、将图像分为文字和非文字的两个类别 8、形态学梯度检测二值图像的边缘 9、形态学实例——从PCB图像中删除所有电流线，仅保留芯片对象(Matlab a variety of image edge detection method 1, using Prewitt operator edge detection image 2, with different values of σ LoG operator edge detection image 3, the detection operator Canny edge image 4, image segmentation threshold 5, water line image segmentation threshold 6, on the matrix quadtree decomposition of 7, the image is divided into text and non-text for these two types of 8, detection of morphological gradient of the edge binary image 9, morphological examples- from the PCB images to remove all current lines, retaining only the target chip)

说明：  反正切函数的变步长算法,能实现反正切函数的变步长的仿真！(Arc tangent function, variable step-size algorithm)

一个非常简易的均线策略，仅作展示用，高手绕行。 5日均线上穿20日均线，做多1手；5日均线下穿20日均线，做空1手； 其中这里上穿、下穿如下定义： 上穿定义：MA5当天大于MA20，前一天MA5位于MA20之下 下穿定义：MA5当天小于于MA20，前一天MA5位于MA20之上 测试数据：IF1112 （2011/5/3-2011/12/8）每日收盘价。 初始资金 50万(a sample back testing matlab code based on ma)
