利用matlab针对图像进行马氏距离计算 ,小波包分析提取振动信号中的特征频率，随机调制信号下的模拟ppm。( Using matlab to calculate the Mahalanobis distance for the image, Wavelet packet analysis to extract vibration signal characteristic frequency, Random ppm modulated analog signal unde.)

该程序能在matlab2009a下运行，运行后能够听到自己的心跳声。注意要带上耳塞并且把音量调到最大(listen to the heart beat)

主要详细的介绍了matlab的一些使用方法，这对于一个新手而言绝对很有帮助(Mainly a detailed description of some use matlab, which is definitely helpful for a novice)

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.)

自编的采用Hough变换的方法估计运动模糊图像的方向，含一个M文件，注释详细，希望对学习图像复原的朋友有一些帮助。(The use of self Hough transform to estimate the direction of motion blurred images, with an M file, comment in detail, hoping to restore the images to the friends learn that some help.)

computes the binomial coefficient C(N,K).
