改进的NHT程序，可以对数据进行归一化，效果较以前的好(improved NHT method)

绘出时域图，在时域上进行分析，提取时域特征值：绝对均值，标准差，有效值，方根幅值，波形指标等等，进行故障特征提取，识别故障(The time domain diagram is drawn and the time domain is analyzed. The time domain eigenvalues are extracted: absolute mean, standard deviation, effective value, square root amplitude, waveform index and so on. Fault feature extraction and fault identification are carried out.)

计算曲面换能器空间各点随时间变化的声场强度，采用的是时间差分法。精度高。(Transducer surface computing space changes over time, each point field intensity, using the time difference. High accuracy.)

说明：  离散型永磁同步电机滑模控制，采用锁相环实现角度估算，角度误差低，效果好。(PMSM_SMO_PLL,test is good.)

A FIS Editor file (.fis file) of an obstacle avoiding robot using Fuzzy Logic.

说明：  pls算法,实现了一个通用的pls算法，可以直接调用。(pls algorithm)

此为《MATLAB教程》的第九章：稀疏矩阵。该书内容翔实，深入浅出，不可多得。(This is the MATLAB Guide in Chapter IX: sparse matrix. Book is informative, easy, hard to come by.)

说明：  基于matlab GUI的数字滤波器源程序(The digital filter based on source code matlab GUI)
