说明：  图像置乱中的仿射变换，优点是加密和解密的不需要周期迭代，图像置乱效果好(it is good for image scrambling becaus of low compute complexity)

PLSA，概率潜在语义算法,用于寻找变量之间的隐隐含变量，常用于图像标注、图像检索、计算机文本检索(PLSA, probabilistic latent semantic algorithm for finding faint containing variables between variables, commonly used in image annotation, image retri , computer text retri )

Matlab讲义高级.rar，PPT课件(Matlab senior notes. Rar, PPT Courseware)

说明：  【 摘 要】 提出了一种基于负熵的快速不动点1 C A算法， 介绍了负熵的定义和如何将其用作代价函数度量混合信号的非 高斯性。 详细介绍了基于负熵的固定点准则以及简化算法。实验选取 3个非高斯向量作为信号源进行 Ma t l a b分离仿真， 结果显示 分离效果良好。 (Abstract Based on the rapid Negentropy 1 CA fixed point algorithm, introduced the definition of negentropy and how to measure its cost function for mixed-signal of the non-Gaussian. Described in detail based on the fixed-point Negentropy criteria and simplify the algorithm. Experiment to select three non-Gaussian vector as a signal source separation Ma tlab simulation results showed good separation efficiency.)

线搜索求简单单峰值函数的最小值程序设计，算法采用固定搜索方向方法。(Simple single-peak line search function to find the minimum programming )

利用前推回代法计算ieee33节点的潮流，计算的速度快，精度高容易收敛。(The forward and backward substitution method is used to calculate the power flow of IEEE 33 nodes. The calculation speed is fast, the accuracy is high and the convergence is easy.)

说明：  主成分分析： (1) 根据指标的属性将原始数据统一趋势化 (2) 利用协方差、相关系数矩阵进行主成分分析，判断可否用第一主成分排名？(Principal component analysis: (1) Unify and trend the original data according to the attribute of the indicator (2) Using covariance and correlation coefficient matrix for principal component analysis, can we use the first principal component ranking?)

Example - 3-D Stem Plot of an FFTFor example, fast Fourier transforms are calculated at points around the unit circle on the complex plane. So, it is interesting to visualize the plot around the unit circle. Calculating the unit circle.(Example- 3-D Stem Plot of an FFTFor example, fast Fourier transforms are calculated at points around the unit circle on the complex plane.
