云南电网结题程序，用于计算110KV侧的电压谐波含量。(Yunnan Power Grid node title procedures ，used to calculate the voltage of 110KV side of the harmonic content)

滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)

OFDM的Matlab仿真源代码，简单易懂，适合初学者迅速上手(OFDM Matlab simulation source code, easy to understand for beginners to get started quickly)

This program shows equalization of OFDM system.

This program basically count every character that is in a text. The program opens de text an reads it, stores data in a matrix and count characters that are in Ascii code and writes the results in a new text file

Practical matlab experiment for charging a capacitor

四足机器人的步态轨迹优化源码，运行main函数即可。(Four-legged robot s gait trajectory optimization code, you can run the main.m function)

用于求解高速球轴承的非线性方程组，输入主程序，用fsolve，可以直接解出来(Nonlinear equations used to solve high-speed ball bearings, input the main program, with fsolve, can be solved directly.)

基于非列排序经济调度问题，比其它算法更好，收敛更好(Based on the column sorting economic scheduling problem, than other algorithms, convergence is better)

说明：  小波去噪程序，在别人的程序上有一定的修改，对于任意声音文件a.wav进行小波去噪。(Wavelet denoising procedure, in others there are certain procedural changes, for any sound file a.wav wavelet denoising.)
