matlab绘图功能，并且有相应文档说明，算法简练，效率较高()

A bad MATLAB data for the algorithm as a DTW model. It can′t recognise the number of 0-9. Do not try it, just do not run testdtw.

这是一个用simulink搭建的经典的跳频模型，对了解跳频有一定的帮助，模型，调试过了，没有问题。(This is a FH model in simulink.)

说明：  实现对故障诊断的主成分分析和主成分,一个很好的效果。(Realize PCA and KPCA on fault diagnosis, a very good effect.)

在matlab，传统的边缘检测直接调用edge函数，但是得到的边缘信息较稀薄，可以通过将sobel,roberts,prewitt三种算子的边缘检测叠加起来，并且对于连续的边缘部分拓宽，使得边缘更连贯清晰(In matlab, traditional edge detection edge direct call function, but thinner than the edge information can be obtained by sobel, roberts, prewitt three edge detection operator stack up, and for widening the continuous edge portion, so that the edge is more consistent clear)

这是数字信号处理做实验的全部程序和内容，很全哦，欢迎下载。(This is to experiment with digital signal processing, all the procedures and content, it all Oh, welcome to download.)
