Algorithm-1

找到一个矩阵里的最小值,因而找到最小值很容易的(find a min number in a matrix,so you can get it essay)

均值滤波：把每个像素周围的8个像素来做均值操作，可以平滑图像，速度快，算法简单，但是无法去掉噪声，只能微弱的减弱它。(The mean filtering: 8 pixels around each pixel do mean, you can smooth image, fast and simple algorithm, but can not get rid of the noise, only faint weakened it.)

说明：  这是一个用Matlab编写的提取图像轮廓并且标示出图像中拐点的例子，输出拐点的坐标。(This is an extract prepared using Matlab image contours and marked a corner in the example image, the output coordinates of corner.)

对比例阀气动伺服系统的matlab仿真，仿真结果良好(Proportional valve for pneumatic servo system, matlab simulation, simulation with good results)

1.本程序是自己刚刚接触SAR时编写的时域星载SAR点目标回波仿真，包含了卫星轨道模型、计算星目斜距时用到的各种坐标系转换、SAR回波计算模型以及简单的SAR成像模型，希望对初学者有所帮助。 2.相应的参考资料可查找《卫星轨道姿态动力学与控制》及《魏钟铨_合成孔径雷达卫星》；(1. This program is just contact with their own prepared when the time domain SAR spaceborne SAR point target echo simulation, contains the satellite orbit model, the satellite project when the use of a variety of slant range coordinate system conversion, SAR echo calculation model and SAR imaging model simple, want to help beginners. 2. The corresponding reference can be to find " satellite attitude and orbit dynamics and control" and " Wei Zhong Quan _ synthetic aperture radar satellites" )

绘制函数的等值线，数值优化书关于约束最优化中实例(Drawing the contours of the function, numerical optimization in the book examples of constrained optimization)

stanford大学开发用于解优化问题的系统模型，可用于解压缩感知恢复算法：BP、DS等(the system modeldeveloped by stanford University is used for the solution of optimization problems, such as compressive sensing recovery algorithm: BP, DS)

Running test programming

通过调用anova1函数作单因素一元方差分析(Anova1 function by calling a dollar for single factor analysis of variance)

这是在matlab编辑环境下开发的关于“图形处理”的实用程序。(This is developed under matlab editing environment on the " graphics processing" utility.)
