最近找的求解方程的程序，可以借鉴下，挺好的(Solving equations to find the most recent program, you can learn, the very good)

matlab求解最优潮流的程序，这个最优潮流可以计算电力系统的潮流(matlab to solve the optimal power flow program, the OPF can calculate power flow)

这是一个OFDM的仿真，里面的untitled.A为主函数，最后出现误码率ber的仿真图(This is an OFDM simulation, the main function inside untitled.A, last seen ber BER simulation map)

说明：  面阵中二维角度DOA估计算法，采用ESPRIT，经典算法，注释清晰，可拿来直接用(Two dimensional angle DOA estimation algorithm in array, using ESPRIT, classic algorithm, clear notes, can be used directly)

说明：  用外点法计算电力系统计算最优潮流，以三机九节点为例，证明了程序的可运行性。(The external point method is used to calculate the optimal power flow of a power system, and the program is proved to be operational by taking three machines and nine nodes as an example.)

说明：  个人总结的matlab常用技巧，主要为输出图表时表格的形式(personal lessons Matlab commonly used techniques, mainly for export charts when a form)

说明：  通过SIMULINK平台建立了3即10节点系统上STATCOM运行的相互影响。(Established by SIMULINK platform that is the STATCOM running on a 10-node system interaction.)

解常微分方程的Matlab程序 字符串ypfun是用以表示f(t, y)的M文件名, tspan=[t0, tfinal]表示自变量初值t0和终值tf y0表示初值向量y0，可选参数options为用odeset设置精度等参数。 输出列向量tout表示节点，输出矩阵yout 表示数值解，每一列对应y的一个分量。若无输出参数，则作出图形。(Solution of ordinary differential equations of the Matlab program is used to indicate ypfun string f (t, y) M-file name, tspan = [t0, tfinal] said that since the variable t0 initial and final values of tf y0, said initial vector y0 , optional parameters to set options for the use of odeset accuracy and other parameters. The output column vector tout that node, the output matrix yout that of numerical analysis, each column corresponds to y of a component. If there are no output parameters, then make a graph.)

说明：  小生境遗传算法工具箱,matlab 7.0(Toolbox of Niched Genetic Algorithm, developed by Matlab7.0.)

boost电路仿真模型，亲测可用，供大家学习参考(boost circuit simulation model, pro-test is available for everyone to learn reference)
