说明：  dfig 基于DQ轴同步旋转坐标轴系数学模型下的双馈发电机simulink (H Fuzzy fangzhen)

NUMERICAL DIFFERENCE APPROXIMATION based on Taylor s expansion---the program give the finite difference coefficient for any number of discrete point. also with that u can differentiate of any function in any order with high accuracy. also u can use it to develop a general finite difference program.

天线实频匹配法优化函数的构造，可扩大频带宽度,达到提高增益的效果(the function structure of the real frequency method)

说明：  在MATLAB中用共轭梯度法求解非线性函数的优化问题。(The conjugate gradient method is used to solve the optimization problem of nonlinear functions.)

别人的测试泊松融合代码，亲测可用。。不过效果不怎么好(possion fusion)

一个关于温度场的Matlab的源程序可以查询不同坐标的温度(A temperature field on Matlab source temperature can query different coordinate)

说明：  C++源代码，递归实现。原问题描述：鼓上蚤时迁到一个山洞里去盗宝，里面有n件宝贝，价值分别是a1,a2......an，并且满足ai大于a1+a2+....+a(i-1)的和。他身上有一个背包，能装的东西最大价值是K，他只能进洞一次，请问他最多能带出多少？ 要求：输入K，n，a1，a2......an 输出：他能最多带出的宝物价值 (C++ Source code Recursive achieve. The original problem description: drum when flea盗宝going to move in a cave, there are n pieces of treasure, valued are a1, a2 ...... an, and to meet ai than a1+ A22B !....+ a (i-1) and. Him to have a backpack, things can hold the greatest value is K, he could only hole once, to ask him to bring out the maximum number of? Requirements: Enter K, n, a1, a2 ...... an output: he can bring out the maximum value of the treasures)

光伏并网逆变器的仿真，通过仿真可以观察逆变以后的波形，有simulink仿真图(PV grid-connected inverter of the simulation, the simulation can be observed after wave inverter, a simulink simulation diagram)

braking of induction motor.

kanon歌曲matlab实现，运行可以听到kanon歌曲的旋律(The kanon Song matlab realize, running can hear the the kanon song' s melody)
