由光学图像生成模拟微波图像，并分为水平极化和垂直极化两种情况(Analog optical image generated by the microwave image)

matlab中的神经网络控制系统工具箱，可以用来方便的开发基于神经网络的控制系统(Matlab the neural network control system toolbox. can be used to facilitate the development of neural network based control system)

MATLAB PROGRAMING FOE ARIMA

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.)

Transforming images from the spatial domain to frequency domain using FFT and DCT, also it includes transforming to the Cepstrum domain.

说明：  伺服阀的详细数学模型，适合初学者研究，可以较方便更改(A detailed mathematical model of servo valve, suitable for beginners study, can be more convenient to change)

基于块对角矩阵的仿真程序，内附注解，非常详细(Block diagonal matrix based simulation program, containing notes, very detailed)
