电力系统分析中Ybus矩阵的去奇异变换法实现算法。该程序可以实现考虑线路分支和无线路分支的情况。(In general the power system has mutual branches and it becomes difficult to form the y bus using the inspection method, so one is to go for singular transformation method.)

说明：  对空间梁单元利用MATLAB进行了编程，仅供参考(The space beam element is programmed by MATLAB, just for reference)

运用分枝定界法求解混合整数规划的matlab程序( Use the branch and bound method for solving mixed integer programming procedures meaning of the of the input parameters: min f* x A* x < = b Aeq* x = beq iter_num_max: maximum number of iterations lb : each variable lower limit UB: upper limit of the each variable X0: Initial ID: 0,1 variable, ID (k) = 1 indicates the variable k is an integer variable, ID (k) = 0, represents the k variable non-integer variable ftemp_up: initial upper bound, unable to find the upper bound of the initial default is infinite IP: initial feasible solution, the initial feasible solution can not be found, the default is the empty output parameters meaning: x: y: optimal solution of the objective function value corresponding to the optimal solution time-consuming iter_num: the number of iterations of the entire branch and bound process Time: Run this program)

matlab反射波正演模拟，学姐编的小程序，欢迎交流(matlab reflected wave forward modeling, sister compiled a small program, please share)

cpm调制解调实现,关联长度为3，调制指数和进制都可调，解调使用vitebi方法(cpm modem realize, correlation length for the 3, modulation index and the band are adjustable demodulation method using vitebi)

使用matlab进行矩阵的高斯分解,可以对高阶线性方程进行数值求解(use Matlab for Gaussian decomposition of the matrix, the high-order linear equations were solved numerically)
