fdtd一维算法，模拟电磁波空间反射散射过程(fdtd one-dimensional algorithm, simulated the process of scattering of electromagnetic waves in space reflection)

将电力市场数据使用小波分解成为两个长度相等的低频和高频小波，然后可以用于灰色模型的建模和波形模型建模！(The electricity market data using wavelet decomposition into two equal length low and high frequency wavelet gray model can then be used for modeling and waveform modeling!)

仿真实现韩老师ADRC书上的P65，有Simulink仿真，s函数的m文件(Simulation to achieve the Korean teacher ADRC book P65, Simulink simulation, s function m file)

对周围相邻的 8 邻居求和（元胞只有两种状态，0 或 1 ）。元胞也有一个单独的状态参量（所谓 记录 ）记录它们之前是否有非零状态的邻居。 在 0 与 1 之间产生一个随机数 r 。 如果总和> 0 （至少一个邻居）并且 r >阈值，或者元胞从未有过一个邻居，则元胞= 1 。 如果总和> 0 则设置"记录"的标志，记录这些元胞有一个非零的邻居。 (8 adjacent neighbors on the surrounding sum (cell only two states, 0 or 1). Cell also has a separate state parameters (so-called ' records' ) record that they have non-zero state before the neighbors. Between 0 and 1 generate a random number r. If the sum of> 0 (at least one neighbor) and r> threshold, or the cell has never had a neighbor, then cell = 1. If the sum> 0 set the " record" sign, record the cell has a non-zero neighbors.)

Compute log(sum(exp(x),dim)) while avoiding numerical underflow. By default dim = 1 (columns).

吉布斯定轨法。 输入：轨道上任意三个点的位矢(R1,R2,R3)； 输出：质点在R2端点时的速度V2；ierr是个判断符号，返回的ierr是零的话，就说明‘R1,R2,R3’共面，如果ierr是1的话说明‘R1,R2,R3’不共面(正常情 况下，要构成轨道的话，‘R1,R2,R3’一定共面 ，即ierr是零，如果ierr是1的话说明输入的‘R1,R2,R3’不共面不能构成轨道。 此函数用于：任意给定三个空间共面的向量，可以确定质点在R2处的速度V2，也就得到了轨道上的一个状态向量(R2,V2),调用前面的函数就可以确定其轨道，及任意时刻的状态。(Gibbs set the track method. Input: track any three points of the bit vector (R1, R2, R3) output: particle at R2 endpoint speed V2, ierr is a judgment symbol, The ierr that is returned is zero, then, it means' of R1, R2,, R3, ' coplanar, if ierr is 1, then description' of R1, R2,, R3, ' not a total surface (under normal circumstances, you want to constitute a track, then,' of R1, R2, R3, ' a certain total surface, ierr is zero, if ierr is an instructions to enter the words ' of R1, R2, R3' coplanarity can not constitute a track. This function is used: for any given three space vector of the surface, can determine the particle at the speed V2, R2 also track a state vector (R2, V2), call the previous function can determine its orbit, and at any time of the state.)
