addmitance matrix for solving load flow analysis

matlab的时频分析工具箱，希望在对信号的分析上可以帮助到大家。(the time-frequency analysis matlab toolbox, hope that the analysis of the signal can help to everyone. )

在过阻尼情况下，典型二阶系统有两个相异的实数极点，其阶跃响应实际上是两个一阶系统响应的叠加。（ωn＝5），不断增大ζ值，观察每个ζ值下两个实数极点间的距离；同时绘出两个实数极点分别对应的一阶系统响应和二阶系统的响应，观察它们间的关系(In the overdamped case, the typical second-order system has two distinct real poles, and its step response is actually the superposition of the two first-order system response. (Wn = 5), increasing zeta values​ ​ , observing the distance between the two real poles each zeta value draw two real poles, respectively, corresponding to a first-order system response and the response of the second-order system, observe them relationship)

惯性导航系统属于一种推算导航方式．即从一已知点的位置根据连续测得的运载体航向角和速度推算出其下一点的位置．因而可连续测出运动体的当前位置。惯性导航系统中的陀螺仪用来形成一个导航坐标系使加速度计的测量轴稳定在该坐标系中并给出航向和姿态角(Inertial navigation system is a dead reckoning navigation mode. That is from a given point according to the measured continuous carrier heading angle and velocity calculates the next location. The current position which can)

在判别分析中使用粒子群优化算法求解最优判别函数(Particle Swarm Optimization(PSO))

说明：  在matlab环境下用智能算法--人工鱼群算法求函数极值的matlab程序(In the matlab environment with intelligent algorithm- artificial fish-swarm algorithm for the extremal function matlab program)

EMD/HHT是一种处理非线性非稳态信号的经典算法，自98年提出以来已经获得广泛的使用，作者huang曾经因次获得NASA的最高奖。(EMD/HHT is a deal with the nonlinear non-stationary signals classical algorithm, since 98 has been raised since the widespread use huang had dimensionless author was NASA's highest award.)

this is an induction motor vector control model in MATLAB/simulink environment.
