母码码率为1/2的LDPC编码 LDPC_QPSK

matlab 将以综合了matlab的各种功能，有很大的用处！！(matlab matlab will combine the various functions is very useful! !)

Matlab code for bilateral filter

简单的PCA主元分析源码，自己编写，亲测可用(Simple PCA principal component analysis of the source code, I have written pro-test available)

径向基函数是一个取值仅仅依赖于离原点距离的实值函数，也就是Φ（x）=Φ(‖x‖),或者还可以是到任意一点c的距离，c点称为中心点，也就是 Φ（x，c）=Φ(‖x-c‖)。任意一个满足Φ（x）=Φ(‖x‖)特性的函数Φ都叫做径向量函数，标准的一般使用欧氏距离，尽管其他距离函数也是可以的。一些径向函数代表性的用到近似给定的函数，这种近似可以被解释成一个简单的神经网络，径向基函数在支持向量机中也被用做核函数。(Radial basis function depends only on the value of a real-valued function of the distance from the origin, i.e. Φ (x) = Φ (x ‖ ‖) or may also be the distance to any point c, c is called the center point , i.e. Φ (x, c) = Φ (xc ‖ ‖). Satisfy any one of Φ (x) = Φ (x ‖ ‖) characteristic functions are called radial vector function Φ standard Euclidean distance is generally used, although other distance functions are also possible. Some typical uses radial function approximation given function, this approximation can be interpreted as a simple neural network, RBF in support vector machines have also been used to make nuclear functions.)

先进PID控制matlab仿真一书的源代码(Advanced PID control simulation matlab book)

说明：  卡尔曼滤波器教程，matlab源码，每一步都有详细的说明，当作入门级教程很好(??????????????matlab?)

说明：  dijkstra算法解决路径规划问题，求解任意两点之间的最小距离(Dijkstra s Shortest Path Algorithm calculates the shortest path and distance between two nodes on a map )

计算电路矢量值，本代码主要计算电路的电流傅里叶矢量，稍加修改就可以用于求电路的电源傅里叶矢量(compute circuit vector)

附件包含离散信道以及各种信道编码的matlab仿真(Annex contains the discrete channels and a variety of channel coding matlab simulation)

说明：  matlab有关K近邻分类算法，很不错，看看(matlab knn )
