bp算法

这两个代码是用贝努利法求方程的最大实根和最小实根，方程只要是标准形式输入参数就可以调用此MATLAB函数(These two functions which are writtern by Matlab can solve out the max and min root through the Benvli method.)

利用matlab计算option的内含波动率(Calculate implied volatility)

利用支路追加法求阻抗矩阵,解：输入数据如下: 请输入节点数:n=a 请输入支路数:nl=b 请输入由支路参数形成的矩阵: B=[i j z bc t it ......]其中ij为支路端点，z为支路阻抗，bc为对地电容，t为变压器变比，it表示i端点是否与变压器直接相连。 (Seek additional method using branch impedance matrix)

pwm半桥逆变,经典案列，经测试没问题，运行很好。PWM half bridge inverter, the classic case, tested no problem, the operation is very good.(PWM half bridge inverter, the classic case, tested no problem, the operation is very good.)

编程仿真连续小推力实现GTO到GEO的三阶段转移过程，其中推力器的推力大小为0.8N，轨道机动的起始点为GTO的远地点。GTO轨道的升交点赤经为0度，近地点角距为90度。 GTO轨道： ph:185km，ah：35786km，i：28.5°，GEO轨道：h：35786km，i：0°。 卫星质量为6600kg，从GTO到GEO，采用5000s的推力器。取地球半径为6378km，g取值为9.8m/s^2(The three stage transfer process from GTO to GEO is realized by simulation and continuous small thrust. The thrust of the thruster is 0.8N, and the starting point of orbital maneuver is the apogee of GTO. GTO orbit RAAN is 0 degrees, 90 degrees for the argument of perigee. GTO orbit: ph:185km, ah:35786km, i:28.5, GEO orbit: h:35786km, i:0. The mass of the satellite is 6600kg, from GTO to GEO, using the 5000S thruster. The radius of the earth is 6378km, and the value of G is 9.8m/s^2)

本程序是利用大气湍流公式对图像进行模糊处理( This program is the use of atmospheric turbulence equations fuzzy image processing)

说明：  对涡结构进行模态降解，可提取尾流的相干结构(The coherent structure of wake can be extracted by modal degradation of vortex structure)

这个是关于图像去噪的程序，对应于《数字图像处理》这本书，主要是关于离散余弦变换变换滤波的以及小波去噪

说明：  互信息配准 本程序是应用灰度互信息进行配准的一个matlab程序(Mutual information registration)
