PCA可用于图像检测的盲取证方面，效果非常好(PCA can be used for blind image forensics testing, the effect is very good)

matlab下对pcm编码进行模拟.可以进一步帮助理解编码过程(right pcm Matlab simulation code. Can help further understanding of the encoding process)

说明：  智能算法三十例，matlab版，希望对大家有用，真心要好好学习一下(this is very good and helpfull to you!)

（注意，之前上传的Fea_Gabor_brodatz有误）该代码为用gabor变换算法提取图像的纹理特征，用matlab编写，可应用于基于纹理的图像检索系统。其中还包含一篇gabor变换相关的文献(The code for the transformation algorithm using gabor texture features extracted using matlab preparation, can be applied to image retrieval system based on texture)

pwe计算方形格子二维光子晶体线缺陷能带的matlab源代码(PWE calculation of two-dimensional square lattice photonic crystal line defect energy band of matlab source code)

利用matlab来实现工程光学里面一些实例，让学生们更容易了解这门学科的更实质性的问题！(Using matlab to achieve engineering optics inside some examples, so that students are more likely to understand this discipline more substantive issues!)

偏最小二乘程序,快速拟合数据，等到一个比较理想的估计值。(Partial least squares procedure, fast fit the data, until a more satisfactory estimate.)

一本很好的教材，讲关于MATLAB-SIMULINK在仿真中的应用(A very good book, talk about simulation and application MATLAB-SIMULINK)

四元数法求解程序，用于求解姿态方程，实现解算对象姿态更新。(Quaternion method solver for solving attitude equation solver object attitude update.)

GprMax的理论基础是时域有限差分(FDTD)方法。时域有限差分方法直接将Maxwell方程作差分离散，利用二阶精度的中心差分近似把Maxwell方程中的微分算符直接转换为差分形式，在空间和时间上对电场和磁场交替间隔取样，使计算过程完全模拟电磁波逐步传播以及与目标物体相互作用的过程。(GprMax is based on the theory of the finite difference time domain (FDTD) method. The finite difference time domain method directly will Maxwell equation of discrete difference, using second order precision of the central difference in the equations are Maxwell approximate differential operator directly convert difference forms, in the space and time of electric field and magnetic field on alternate sampling interval, making the calculation process simulation electromagnetic wave propagation and completely step by step and target object interaction process. )
