人工鱼群算法

这是一篇关于压缩检测的文章，稳重利用压缩感知的方法来解决通信系统中二元信号检测问题。(This is an article about the compression test, steady use of compressed sensing approach to solve the communication system with binary detection problem.)

说明：  差分进化程序，有注释，可以直接修改函数运行！(Differential evolutionary process, there are notes, you can directly modify the function to run!)

沿螺钉螺旋线提取ct图像中的椎弓根骨密度(extraction of pedicle bone mineral decsity from CT images along screw helix)

把经纬度表示的两个点转换为两点距离或以第一个点为原点的第二个点的XY坐标(Convert 2 points described in Longitude and Latitude to their distance or coordinate.)

A demo showing how work the basic active conter method (snakes).

通过输入关参数，求相得四阶累积量。方便的解决了求四阶累积量的计算复杂问题。(Through the input parameters, phase fourth order cumulants. Convenient to solve the fourth-order cumulant of calculating the complex problems. )

编写查找程序search，功能如下：给定任意有序数列，然后输入任意一数，用折半查找法找出该数在数列中的位置，若数列中有此数，则返回该数在数列中所在的位置，若数列中无此数，则返回-1 把给定值y插入到有序数组a（由大到小）中，插入后，数组中的数仍然有序 用递推法求解：一串字符以问号“？”结尾，顺序读入后反向输出，且统计其中字符的个数(prepare you search procedures, functions as follows : Given a series of arbitrary order, then enter an arbitrary number, using binary search method to find the few series in the position, if the series is this, Return of the few series in the location, if the series has been no such number,-1 is returned will be distributed to value y orderly array inserted into a (decreasing), insert after The array is an orderly with a few recursive method : a bunch of characters with a question mark "?" The end of the order after reading the reverse output and statistics on the number of characters)

二维波导中计算反射系数，两边为PML，上下为PEC，波源为平面波(two-dimensional waveguide reflection coefficient calculated on both sides of the PML and bottom of the PEC, for the plane wave Boyuan)

混沌理论预测方法，可以进行多步骤预测，方便使用，很用的工具。(chaos a very good sofeward if you have you will find very goog)

离散粒子群算法。粒子群算法原来只能处理连续变量，算法进行了改进，可以处理离散变量(Discrete particle swarm optimization algorithm, particle swarm optimization algorithm can only deal with continuous variables, the algorithm is improved, can handle discrete variables )
