基于共轭梯度法为最优控制的几个源的自适应控制

地震断层旋转功能，把地震断层按研究需要旋转到一定角度。(Earthquake fault rotation function, according to the research needs of earthquake faults rotated to a certain angle.)

这是一本国防电子信息技术从书中的一本——合成孔径雷达成像 算法与实现，是Ian G. Cumming[美]编写的，由洪文等翻译的。(This is a national defense electronic information technology from the book - Digital Processing of Synthetic Aperture Radar Data Algorithms and Implementation, is written by Ian G. Cumming [US], translated by Hong Wen et al.)

说明：  使用matlab中的多个命令来画出二维、三维的图像(Using matlab multiple commands to draw two-dimensional, three-dimensional images)

这是求信噪比的程序，就是信息噪声功率比上噪声功率(This is the signal to noise ratio for the procedure is, the information on the noise power ratio noise power)

The Rough Sets experiments - Attribute Reduction(The Rough Sets experiments- Attribute Reduction)

matlab写的一个产生蜂窝的程序，很漂亮(write a matlab generated cellular process, it is beautiful)

说明：  PLS_Toolbox是用于故障检测与诊断方面的matlab工具箱，其中包括PCA、PLS等(Pls _ toolbox is a matlab kit for fault detection and diagnosis, including a variety of algorithms such as pca, pls, and subsequent processing: q statistics, t2 statistics, and so on.)

才用周期图法预测hurst指数。参数sequence为时间序列，isplot说明是否需要画图。(Have used the periodogram forecast hurst index. Parameter sequence for the time series, isplot explain the need for drawing.)

使用改进后的全变分算法对地震剖面进行处理，可以提高地震剖面的分辨率，增加信噪比。(Using the improved algorithm, total variation seismic processing, can improve the resolution of seismic profiles, increased signal to noise ratio.)

DFT进行频谱分析时的三种现象 1、混叠：对连续信号采样，要求连续信号是带限的，采样频率要足够高。Fs应满足Nyquist采样定理才不产生混叠。 采样前加低通滤波器防混叠 2、频谱泄漏：DFT对时域信号进行了截断（相当于采样信号乘了一个窗函数），时域的乘积相当于频域卷积，改变了原信号频谱。 改用其他窗函数（非矩形）改善泄漏。 3、栅栏现象：DFT 只给出了频谱在采样点上的取值，采样点间的频谱内容丢失。(DFT spectrum analysis of a three phenomena, aliasing : continuous signal sampling, requiring continuous signal is band-limited, the sampling frequency should be high enough. Fs meet the Nyquist Sampling Theorem would not have aliasing. Sampling former low-pass filter plus anti-aliasing 2, spectrum leakage : DFT right time domain signal a disconnect (equivalent to a sampling signal by a window function). time domain is equivalent to the product of frequency-domain convolution, changes in the spectrum of the original signal. Window functions to switch to other (non-rectangular) to improve leakage. 3, fenced phenomenon : DFT spectrum is given only at the sampling point value, sampling points of the spectrum as lost.)
