shear-flow

This a collection of MATLAB functions for extended Kalman filtering, unscented Kalman filtering, particle filtering, and miscellaneous other things. These utilities are designed for reuse and I have found them very useful in many projects. The code has been vectorised for speed and is stable and fast.

非下采样轮廓波变换，NSCT变换，主要用于图像去噪，效果非常不错(Nonsubsampled contourlet transform, NSCT transform, mainly for image denoising, the effect is very good)

使用FPE准则，绘制不同阶数的FPE值，确定最优阶数(Using the FPE criterion, the FPE values of different orders are plotted, and the optimal order is determined)

Random processes important papers from previous years.

一个基于MATLAB环境开发的扑克牌识别程序，个人觉得很不错，在此与大家分享一下！(MATLAB-based environment for the development of procedures to identify playing cards, personal feel very good in this to share with you some!)

说明：  用schwarz电弧方程建立的电弧仿真电路，可用于观察燃弧期间的电弧电压和电流、电导，(a simulation of schwarz arc model using matlab,)

方波图形，简单的图形，仅供参考，主要是对于初学者(square graphics, simple graphics, for reference purposes only, primarily for beginners)

Matlab中有很多根据多边形顶点计算多边形面积，对多边形涂色等函数，但是并没有对多边形顶点进行凸多边形排序问题，所以写了这个对可以构成凸多边形的顶点进行排序的算法。( 此子程序功能为逆时针排列多个可构成一个凸多边形的顶点 输入参数xv是这些顶点的横坐标集合 yv是这些坐标的纵坐标集合 返回的排列好的点的横坐标和纵坐标集合. 使用示例: [x y]=rangePolyponPoint([0 10 10 0],[0 10 0 10]) 输出结果为：x = [ 0 10 10 0], y = [ 0 0 10 10].)

说明：  采用四元数法的标准圆锥运动的姿态角仿真程序，。(Quaternion method using the standard cone movement attitude angle simulation procedures.)

对一组具有相似模式的数据进行聚类，并且进行可视化(SOM)
