程序

一个simulink的仿真课件，通俗易通，自己感觉挺好(A simulink simulation courseware, popular ETS, he felt very good)

matlab中的psat软件可以用于潮流计算，连续潮流计算，小扰动分析，分岔分析等等，这是三个版本的说明书(psat matlab software can be used in the flow calculation, continuous flow calculation, the small perturbation analysis, bifurcation analysis, etc., which are the three versions of the manual)

最近有人问我关于什么时候用self.赋值的问题, 我总结了一下, 发出来给大家参考. 有什么问题请大家斧正.(Recently someone asked me about when to use self. Assignment, I sum up a bit, given to your reference. Have any questions please Fu Zheng.)

此算法为用于解反问题的lsqr算法，对Ax=b，输入矩阵A，列向量b，以及迭代步数，求得列向量x(This algorithm is used for solution of the inverse problem lsqr algorithm, Ax = b, the input matrix A, the column vector b, as well as the number of iterative steps, to seek the column vector x)

matlabFastICA程序，用于语音处理，例程中有两个独立源(matlabFastICA program for voice processing, the routine has two independent sources)

this matlab code is for drawing histograms of distributed/normal random samples,basic operations on signals as addition, multipication,delay.Drawing spectrum of signal.

对示波器或其他设备在实验中接收并储存的离散信号进行绘图，行程信号曲线图(Oscilloscope or other device is received and stored in the experiment drawing discrete signals, the signal graph stroke)

利用matlab进行时域分析，本实验首录了三个音频。并编写程序求其特征值。特征值有平均值，整流平均值方差，标准差，方差，峭度，均方根，波形因子，峭度因子，峰值因子，脉冲因子，裕度因子。还有就是对音频进行自相关分析得出其波形图。(Use matlab time-domain analysis, the first experiment recorded three audio. Programming and seeking the eigenvalues. Characteristic values are averaged rectified mean variance, standard deviation, variance, kurtosis, RMS, crest factor, kurtosis factor, crest factor, pulse factor, margin factor. There is an audio self-correlation analysis of its waveform.)

小波包分析提取振动信号中的特征频率，最终的权值矩阵就是滤波器的系数，可直接计算得到多重分形谱。( Wavelet packet analysis to extract vibration signal characteristic frequency, The final weight matrix is ??the filter coefficient, It can be directly calculated multi-fractal spectrum.)

利用MATLAB开发软件进行编程，实现了数字IIR低通滤波器的功能，程序直接可以运行！(Use MATLAB to develop software for programming, implementation of digital IIR low-pass filter function, the program can run directly!)
