这个命令是用Matlab编写的小波分解，希望对大家有用(This command is written in Matlab wavelet decomposition, we hope to be useful)

Vim用户手册中文版72，非常好的VIM使用手册，方便辅助开发(Vim user manual Chinese version of VIM 72 very good manual, easy to supporting development)

采用有限元法利用matlab编制了管道的自振频率计算程序。(The finite element method using matlab to prepare a pipeline vibration frequency calculation procedures.)

matlab的knn网络，最小二乘算法，softsvm分类器实现，以及简单的交叉验证等，三种产检的方法(knn，softsvm matlab)

一个很好用的图像GHM多小波变换程序,实现一阶变换(a very easy function for GHM，can do first GHM transform.)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)
