这是一个用VC编写的FIR低通滤波器，通过加汉宁窗实现。其中可以按照各种设计要求得到不同冲激响应的FIR滤波器，并能通过设计好的滤波器计算它的最小阻带衰减，以检查所设计的滤波器是否满足设计要求

这是一个数学计算方面的C程序-This is a mathematical calculation of the C program

数值分析中常用的几种算法的实现-numerical analysis of several commonly used algorithms to achieve

在日常的生活中我们最经常使用的距离毫无疑问应该是欧式距离，但是对于一些特殊情况，欧氏距离存在着其很明显的缺陷，比如说时间序列，举个比较简单的例子，序列A：1,1,1,10,2,3，序列B：1,1,1,2,10,3，如果用欧氏距离，也就是distance[i][j]=(b[j]-a[i])*(b[j]-a[i])来计算的话，总的距离和应该是128，应该说这个距离是非常大的，而实际上这个序列的图像是十分相似的，这种情况下就有人开始考虑寻找新的时间序列距离的计算方法，然后提出了DTW算法，这种方法在语音识别，机器学习方便有着很重要的作用。 这个算法是基于动态规划（DP）的思想，解决了发音长短不一的模板匹配问题，简单来说，就是通过构建一个邻接矩阵，寻找最短路径和。 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
