least square SVM toolbox

说明：  计算机视觉的一个典型应用。使用SIFT方法做特征提取，然后用于拼接。(A typical computer vision applications. SIFT feature extraction method used to do, and then used for splicing.)

计算机控制系统5道大题作业，有详细求解过程及相应的matlab程序。(five task of Computer Control System with detail solution and conresponding to matlab programing)

Three phase curretn loop invereter

说明：  基于matlab简单图像处理系统中对图片的加噪功能(Based on a simple matlab image processing system for image plus noise functions)

一个快速k均值彩色图像的分割算法，运行环境是matlab！(A fast k-means algorithm for color image segmentation, the operating environment is matlab!)

slam代码，扩展卡尔曼滤波，输入时两个轮子的速度以及采集到的Landmark标志点与移动机器人的相对坐标(slam code, extended Kalman filter, the input speed of the two wheels, as well as the acquisition Landmark signs point to the relative coordinates of the mobile robot)

说明：  在数学建模当中，粒子群算法的通用案例，只需要修改核心算子——适应度即可。(In mathematical modeling, the general case of particle swarm optimization only needs to modify the core operator fitness.)

the comb pilot aided channel estimation in ofdm modulation is considered. the power of pilot subchannels is under the control. The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

说明：  文章中介绍了matlab的所有重要命令，能够满足简单matlab编程的需求(Matlab article describes all the important orders, to meet the demand for simple programming matlab)
