无约束问题最优化方法的核心问题是选择搜索方向。 以正定二次函数为例，来观察两个方向关于矩阵Ａ共轭的几何意义(Unconstrained optimization problems are most core issue is to choose the search direction. In definite quadratic function, for example, to observe both directions on the matrix A conjugate geometric meaning)

说明：  statcom的simulink实现，采用dq解耦法控制。(STATCOM is built in Simulink, and DQ decoupling method is used to control.)

二相编码信号的产生以及频谱分析，可以产生7位、11位、13位典型编码信号以及13位bark码的频谱图，通过仿真可用(Two-phase coded signal generation and spectrum analysis, can produce 7, 11 and 13 typically coded signals and 13 yards of bark frequency spectrum, through the simulation can be used)

这是关于偶极子天线的仿真程序。模型搭建合理，仿真结果包括电场、磁场、电压电流的分布图，还包括偶极子天线的磁场三维视图。(This is a simulation program on the dipole antenna. To build a reasonable model, the simulation results, including the electric and magnetic fields, voltage and current distribution maps, also includes a magnetic field three-dimensional view of the dipole antenna. )
