Laplacian_Smoothing_Transform

此段代买可以用来实现层次分析法，通过输入参数、更改参数，利用循环自动检验是否符合层次分析法的要求(solve the AHP problem)

Reduce the number of data points using a spanning tr(Reduce the number of data points using a spa nning tr)

说明：  第二种孤岛运行的控制是采用下垂控制（droop控制），Droop控制就是用来模拟频率一次调整。通过控制电力电子逆变器来实现。(The second kind of island operation control is droop control, Droop control is used to simulate a frequency adjustment. It is realized by controlling the power electronic inverters.)

说明：  使用matlab工具对sonar数据集进行kmeans分类(Kmeans classification of sonar data set with MATLAB)

不同信道条件下码间串扰的情况，包括波形图和眼图。(Under different channel crosstalk between code, including waveform and eye diagram.)

MATLAB开发的常用的数值分析代码,用以解决常用的数值分析组合，集成设计(MATLAB Athoritic )

故障诊断matlab源代码，能够正确识别故障的类型(Fault diagnosis matlab source code, able to correctly identify the type of fault)

已知一个序列x(n)=0.5cos(0.55*pi*n)+cos(0.45*pi*n),时域FFT分析其频谱。 （1）使用不同宽度的矩形窗截断该序列为M点，取M分别为：20，40，160,观察不同长度对频谱影响；（2）使用哈明窗和凯泽窗重做；（3）对三种窗的结果进行分析比较；（4）总结窗类型和长度对频谱分析的影响。 (Known a sequence x (n) = 0.5cos (0.55* pi* n)+ Cos (0.45* pi* n), time-domain FFT analysis of its spectrum. (1) use a different width of the rectangular window of the sequence for M cut-off point, take M are as follows: 20,40,160, observing the impact of different lengths of the spectrum (2) the use of Hamming window and the Kaiser window redo (3 ) on the three windows analyzed and compared the results (4) summarize the type and length of window for spectrum analysis.)

岭回归程序 输入参数为自变量、因变量和优化因子 输出参数为映射矩阵与回归误差(Ridge Regression. Input parameters: - X: Input data block (k x n) - Y: Output data block (k x m) - q: Stabiliaztion factor (optional) If not given, estimated from data Return parameters: - F: Mapping matrix, Yhat = X*F - error: Prediction errors)
