Introduction to MATLAB and Simulink Third Edition

基于matlab的人脸识别程序，内附说明，很详细(Matlab-based face recognition process, containing a description, in detail)

说明：  合成孔径雷达图像处理中最简单的情况，单个点目标的回波模型(sar)

说明：  无约束一维极值问题中的可接受搜索法，例程可调(Unconstrained extremal problem in the one-dimensional search method acceptable, routine adjustable)

在MATLAB环境下四个实验,压缩解压以便日后使用(change picture)

根据对真空蒸发镀膜的分析，在40×40的范围内分别蒸 发：1000、5000、10000、20000、30000个粒子。  利用2维数组记录每个点的粒子数。  初始粒的横纵坐标为0～40的均匀分布。  能量为（15，3）的正态分布。  在基体表面自由行走时损失1的能量。  若该点有粒子，即与其他粒子相遇时损失3的能量。  由低处向高处扩散，每扩散一层，损失4的能量，由高处 向低处扩散，损失3的能量。  当粒子的能量小于等于0时停留下来，该点的粒子数加1。  临界核的尺寸为10个粒子。  根据每个点粒子个数的不同，以不同的灰度显示这些点。 点越亮，则表示该点的膜越厚。  以图形方式显示粒子初始能量的正态分布情况(Based on the analysis of the vacuum evaporation coating, respectively, in the range of from 4040 evaporated: 1000,5000,10000,20000,30000 particles.  each point using 2-dimensional array to record the number of particles. The  initial grains transverse and longitudinal coordinates of a uniform distribution of 0 to 40. The  energy as a normal distribution (15,3).  1 energy losses in the substrate surface to walk.  point particles that 3 energy loss in the encounter with the other particles.  by the lower diffusion tops every diffusion layer, a loss of 4 energy diffusion from high to low, the energy loss of 3.  When the energy of the particles is less than or equal to 0:00 stay down, add 1 to the number of particles that point.  critical nucleus size of 10 particles.  these points, depending on the number of particles of each point is displayed in a different shade. Point, the brighter, the thicker the point of the fi)

说明：  多分类孪生支持向量机,主体是-1 1的2分类孪生支持向量机，采用onevsone改编成多分类的孪生支持向量机(multi classification twin support vector machine, kernel code is binary-classification twin support vector machine ,constructed it as a multi classification twin support vector machine by using OneVsOne coding)

一个基于DCT域的数字水印代码，里面有详细的注释说明。(This is a digital watermarking sourcecode based on DCT.Attached with detailed comments and explanation.)
