超效率DEA

this ring buffer sample.

采用余数法产生一组[0，1]分布的随机数，产生一个N(0,1)正态分布随机数，产生n个N(a,b)正态分布随机数(Produced by a group of more than a few method [0,1] distributed random numbers to generate a N (0,1) normally distributed random numbers, resulting in n-N (a, b) normal random number)

对齿轮箱故障进行提升小波去噪分解重构，准确判断初故障类型(Gearbox fault on lifting wavelet de-noising decomposition and reconstruction and accurately determine the beginning of the fault type)

This is a matlab file that is simulating minimum shoft keying signals. This is a simulink file and pulse shaping is also used in it.

小波包分析提取振动信号中的特征频率，真的是一个好程序，窗函数法设计一个数字带通FIR滤波器。( Wavelet packet analysis to extract vibration signal characteristic frequency, Really is a good program, A window function design FIR digital band-pass filter.)

学习matlab，用c语言读wav格式的必备资料；自己写的寻找一组数据的峰值点程序，提取信号包络的程序，小波工具箱(Learning matlab, using c language read wav format necessary information their search for a set of data written in the peak-point program, extract the signal envelope of the process, wavelet toolbox)

说明：  simulink初学者快速入门的好帮手，我开始就是学的这个，很快入门(good)

通过输入相关参数，实现三阶累积量的求法。从而避免复杂的计算过程。(By input parameters, the third order cumulant method. To avoid complex calculation process. )

matpower4.1相关文件，用于实现matpower仿真30节点数据(matpower4.1 relevant documents for the 30 node data matpower simulation)

its help ful for learning adaptive filter I hope that you have good learning adaptive filter
