海面上一轮船沿直线匀速前行，速度为30公里/小时，船上有一雷达可用来测距、测角，船长关心的是周围目标那些是活动的船，那些是不动的岩石，若是活动的船，请按下面假设，分析有关因素，给出船的运动方向和速度。(ships on the sea along a straight uniform before the trip and a speed of 30 km/hour, On board there is a radar can be used to measure the distance and angle measurement, the captain of concern is around the goal of those activities is the boat. those are immobile rocks, if the ship by the following assumptions, analysis of the relevant factors, the boat is the direction and speed of movement.)

bp-pid算法，自己编写的，关于一个非线性求解的实际例子(bp-pid algorithm, I have written about the actual example of a nonlinear solution)

岭回归函数，基于SVD分解的岭回归函数，已经证明了是非的有用和强大( center input and output, so we can estimate w0 separately since we don t want to shrink w0 )

使用遗传算法优化fcm算法对初始值敏感的问题，得到全局最优解，求出聚类中心作为fcm算法的输入(Using genetic algorithm and optiml fcm algorithm solving initial,get the best solution and make the initial cluster to be the input)

利用分数阶傅立叶变换进行信号参数估计，本程序是对LFM信号的参数中心频率和调频斜率进行估计(Use FRFT signal parameter estimation, the parameters of this program is the center frequency and frequency rate LFM signal is estimated)

用LAPLACE方法求解多维沃尔泰拉方程，此处为一个变元的方程，由于该方程同时含有微分和积分，一般求解有一定的困难。此处为MATLAB程序，注意不同的初始条件(used method for multiple preoperational Ertaila equation here as a variable element of the equation, As the same time contain differential equations and integral, the general solution is definitely difficult. MATLAB here for the procedure to different initial conditions)

针对多椭圆检测问题提出了一种快速随机检测算法。该算法利用在图像中随机采样到的一个边缘点和 局部搜索到的两个边缘点以及这三个点的邻域信息确定候选椭圆,再将候选椭圆变换为对应圆,通过确认真圆来确 认真椭圆。在确定候选椭圆时,最大限度地减少随机采样点数‰ 剔除更多的非椭圆点,降低了无效采样,减少了无效 计算。数值实验结果表明:该算法具有良好的鲁棒性,其检测速度比同类算法快(Ellipse detection problem for many a fast random detection algorithm. The algorithm uses random sampling in the image of an edge point and the local search to the two edge points, as well as the three-point neighborhood information to determine the candidate ellipse, and then transformed into the corresponding elliptical candidate won, through the identification of real yen to confirm really elliptical. In determining when a candidate ellipse, to minimize random sampling points ‰ remove more non-oval points, reducing invalid sampling, to reduce the calculation invalid. Numerical experimental results show that: the algorithm has good robustness, and its detection faster than similar algorithms quickly)

dq transformation for filters..it s very good example..

Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal

说明：  Matlab的数理统计工具箱是Matlab工具箱中较为简单的一个，其牵扯的数学知识是大家都很熟悉的数理统计，出数理统计工具箱的一些函数，这些函数的意义都很明确，使用也很简单，为了进一步简明，本文也仅仅给出了函数的名称，没有列出函数的参数以及使用方法，大家只需简单的在Matlab工作空间中输入“help 函数名”，便可以得到这些函数详细的使用方法。(Mathematical Statistics Matlab toolbox Matlab toolbox is a relatively simple, the mathematical knowledge involved are very familiar with the U.S. mathematical statistics, mathematical statistics toolbox out some function, the significance of these functions are very clear, use is also very simple, for further simplicity, this article only gives the function name, function parameters are not listed and the use of methods, the U.S. simply working space in Matlab, type )
