学习MATLAB的基本应用与MATLAB仿真的基本知识，适合初学者(Learning of MATLAB applications and basic knowledge of MATLAB simulation, suitable for beginners)

Buck modeling Matlab/Simulink

说明：  进行有关权值训练，得到相应的最优解,并将所训练的样本进行分类。(About Weight Training optimal solution to give the corresponding)

Harris corner extraction matlab code，摄像头标定时采用的角点检测方法，用于提取角点像素坐标。(Harris corner extraction matlab code, camera calibration using corner detection method for extracting corner pixel coordinates.)

Zernike transforms is one of the best extraction feature tools for image

绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

图像隐藏和数字水印。采用在空域隐藏，在每个象素的bit位的低位藏入图片。采用在DCT系数上附加信息的方法进行。(image hiding and digital watermarking. Hidden in the airspace used in each pixel of the low bit-into the possession of photographs. Using the DCT coefficient Additional information on the methods.)

phase field simulation example which use the LBM modle。 It s very useful.

说明：  matlab的TDOA定位，分LOS和NLOS(TDOA location based on MATLAB)
