GPS-Acquisition-Algorithm

This program return the average centrality for a graph for different value of x.

matlab方面有很多程序可以使用到学习与工作中(matlab, there are many programs you can use to learn and work)

说明：  一些有关最优控制理论的控制实例程序集仿真 (Optimal control theory control instance assembly)

说明：  viterb算法是卷积码中重要的一种译码算法，程序中用MATLAB实现了VITERB的译码算法，并且写了信道编码程序和二进制码通过以p概率错误的信道程序(viterb algorithm is important as a convolutional code decoding algorithm, the program using MATLAB to achieve a VITERB the decoding algorithm, and wrote letters Road, binary coding process and the probability of error through a p-channel process)

已知n个城市之间的相互距离，现有一个推销员必须遍访这n个城市，并且每个城市 只能访问一次，最后又必须返回出发城市。如何安排他对这些城市的访问次序，可使其 旅行路线的总长度最短？ (known cities between the distance from the existing one must salesman n visited this city, every city and can only be visited once, finally starting to return to the city. How to arrange for him to visit these cities priorities, it can travel routes, the total length of the shortest?)

RNW_perm(A) 利用Ryser-NW方法，计算n*n矩阵A的积和式。计算时间随着n 以2的指数倍增长。计算20*20以内的矩阵很快。 Hperm(A) 利用双元素展开计算非常稀疏的矩阵的积和式 symmRegular(n,k,m) 该命令要调用symmGen函数。 生成对称的k-regular n阶0-1矩阵的启发式算法。 参数n,k是必须的。m的默认值是10。 m设定尝试次数，如果该命令显示 fail ,表明经过m次尝试， 没有生成满足条件的矩阵。 symmGen(n,k) 这里k是一个n维向量，该命令启发式地生成一个以k为行和 的对称0-1矩阵。不能保证每次都成功，不过成功的概率一 般情况下尚可接受。(some useful code for numerical analysis)

这个是pm方程的自适应小波阈值改进,使阈值可以自适应(This is the adaptive wavelet threshold PM equation is improved, which can be adaptive threshold)

数据处理及误差分析采用了matlab软件来实现，它的界面虽然没有VB等直观简便，但其可调用的函数多，实现起来比较方便，程序中已经实现的功能有： （1）求算术平均值； （2）求残余误差（绝对误差）； （3）求标准差； （4）判断粗大误差，如果发现粗大误差,剔除粗大误差后再进行计算； （5）判断数据是否具有线性误差或者周期性误差。 (Data processing and error analysis using matlab software to achieve, its intuitive interface, while not VB so simple, but its function can be called many realize it was easier, the program has been implemented features are: (1) Find the arithmetic mean (2) Find the residual error (absolute error) (3) Find the standard deviation (4) to determine gross error, if found to gross error, calculated after excluding gross error (5) to determine whether data has linear error or Periodic error.)
