这是求解用户位置的MATLAB函数代码,可以通过设定卫星的坐标,模拟仿真用户的位置(This is the location of the user of the MATLAB functions for solving the code, you can set the satellite coordinates, the location of the user simulation)

说明：  提供了人工鱼群算法和RBF神经网络代码，有需要的朋友可以下载参考(AFSA offers and RBF neural network code, a friend in need can be downloaded for reference)

自己写的用Matlab模拟一个缓冲区大小（包括正在服务的那个）为10的随机排队系统。 （1）到达过程是的泊松过程（到达速率为Mu），服务时间服从独立指数分布（均值为1/Lamda）。 对Mu//Lamda=0.2，Mu//Lamda=0.8和Mu//Lamda=1.1三种情况进行仿真，求出队列中接受服务用户为n的概率P(n), n=0,...,10。并与理论结果进行比较。 （2）假设到达过程为均匀过程（到达速率为Mu），服务时间服从独立瑞利分布（均值为1/Lamda）。(yourself writing a simulation using Matlab buffer size (including services that are) for the following 10 Machine queuing system. (1) arrival process is the Poisson process (arrival rate of Mu), submit to independent service index distribution (mean of 1/Lamda). Right Mu// Lamda = 0.2, Mu// Lamda = 0.8 and the Mu// = 1.1 Lamda three of the simulation, Queue calculated users receive services n the probability P (n), n = 0 ,..., 10. And with the theoretical results. (2) It is assumed that the arrival process for the uniform process (arrival rate of Mu), submit to independent service Rayleigh distribution (mean of 1/Lamda).)

说明：  最炫民族风的源代码，喜欢的可以下载下来，放在matlab中听一下。另外，这里还有其他音乐代码，需求的可以私信我。(The most unusual national wind source code, like you can download and put matlab liking it. In addition, there are other music code, demand can private letter to me.)

optics密度聚类源码，简单容易理解，止血药修改ReadTxt.m中的load的传入，就可以直接运行。(Called density clustering source, simple and easy to understand, hemostatic changes ReadTxt. M of the introduction of the load, can be directly run.)

+1A 是!" 世纪$" 年代中期发展起来的用于模拟流动现象的计算方法( 它从分子运动论统计力学的观 点和理论出发，以微观的粒子尺度为基础，建立离散的速度模型，在满足质量、动量和能量守恒的条件下，得 出粒子分布函数，然后对粒子分布函数进行统计计算，得到压力、流速等宏观变量( 其主要思想就是以简单规 则的微观粒子运动代替复杂多变的宏观现象，用迁移和碰撞两个相对简单的过程再现流体的宏观特性。(Lattice boltzmann studies of fluid flow)

说明：  应用在认知无线电频谱检测中。环境：经过加性白噪声的信号。功能：求解虚警概率和漏检概率。(Used in cognitive radio spectrum detection.Environment: after additive white noise signal.Function: to solve the false alarm probability and missed detection probability.)

说明：  有限体积法,通过有限体积法求解naca0012流场，通过有限体积法求解naca0012流场(finite volume method)
