Matlab中用到的部分函数列表，按功能分类(Part of the list of functions used in Matlab, classified by function)

初学matlab的教程，比较全面，比较实用，此部分为第三部分。(Matlab beginner tutorial, more comprehensive, more practical, this part of the third section.)

clustering algorithm

源代码在matlab实现相邻帧间差分法对于视频中对移动目标的识别。附送视频，在matlab上能打开的视频只有无压缩的AVI视频。视频背景没有变化的情况下，处理效果很好。(The source code in matlab between adjacent frame difference method for the recognition of moving target in the video. Attached to the video, can open the video on the matlab only compressed AVI video. Does not change the background of video cases, the treatment effect is very good.)

MATLAB信号处理必不可少的滤波器设计全解(MATLAB signal processing filter design essential to the whole solution)

说明：  在共梯度法中 只有当初值的选取靠近最优解时 迭代才会收敛 当远离时发散 且 当精度控制为0.1时可以实现 但设为0.01时就实现不了(numubrical)

摘要:为提高密码的抗攻击性,利用超混沌系统随机性好!可确定再生,且密钥空间较大的特性,提出了一种基于四维连续超混沌系统和扩展映射的实时视频流加密算法"(Abstract: In order to improve the password anti-aggressive use of system randomness hyperchaos good! Regeneration can be identified, and key characteristics of the larger space, a row based on four-dimensional hyperchaotic system and expansion of mapping real-time video stream encryption algorithm )

说明：  测量图片中的建筑物角度，R2008B以上版本运行(Measurement of the angle the picture of the building, R2008B or later to run)

绘制极坐标图函数，绘制多条时，是将参数组成行向量(Draw polar plot function to draw multiple parameters composed of row vectors)
