matlab《主成分分析》的源代码,是化学计量学的模式识别的主要程序。(matlab )

这是一本很少见的中文matlab帮助手册，特别对于点运算等入门级知识进行了详解，大家共享吧！(This is a very rare Chinese matlab help manual, particularly for entry-level point of computing, such as the detailed knowledge, share it!)

该协议是LEACH的改进，思想是：为了延长网络的生命周期，节点只需要和她们最近的邻居之间进行通信。节点与汇聚点间的通信过程是轮流进行的，当所有节点都与汇聚点通信后，节点间再进行新一回合的轮流进行的。由于这种轮流通信机制使得能量消耗能够统一的分布到每个节点上，因此降低了整个传输所需要消耗的能量。(The agreement is LEACH improvement idea is: To prolong the network lifetime, and between nodes only need to communicate with their nearest neighbors. Communication process between the node and the focal point is in turn carried out when all the nodes are associated with the convergence point communication between nodes then turns a new round of. Due to this rotation so that the energy consumption of the communication system on each node to the uniform distribution, thus reducing the energy consumption required for the transmission.)

将音乐信号fm调制并解调，光看波形和频谱(Fm music signal modulation and demodulation, optical waveform and spectrum look)

已知观测数据为A+W(n)，其中A为直流信号，W为复高斯噪声，服从CN（0， ），在统计N次下，计算X的统计平均值 ，求T(x)= 的pdf：p(T(x)|H0)、p(T(x)|H1)。 H0： W H1： A+W (Known observation data A+W (n), where A is the DC signal, W is the complex Gaussian noise, subject CN (0,), N times in the statistics, the calculation of the statistical mean of X, find T (x) = a pdf : p (T (x) | H0), p (T (x) | H1). H0: W H1: A+W)

说明：  是cso得源代码，里面有详细的写法，主要有速度和位置更新公式(It is the source code of cso, which has detailed writing, mainly including speed and position update formula)

灰色预测，简单的编程，大家多提意见(Gray forecast, a simple programming, we do so!)

一种对图像滤波的matlab程序，能够去除很严重的椒盐噪声，带有很详细的注释，很容易看明白！(a pair of image filtering Matlab procedures to remove a very serious Impulse noise, with a very detailed notes, it is easy to see the truth!)

pid算法原理解释，对初入学习PID的同学有很大帮助(pid algorithm principle explanation for entering the learning of the students are very helpful PID)
