2d heat conduction problem in matlab

matlab下几种调制函数，包括fskmod,pskmod等的使用，部分有翻译，版本为7.0 (matlab under the modulation of several functions, including fskmod, pskmod such as the use of some translation, version 7.0)

模糊自适应推理系统的程序，用过效果挺好。(Adaptive fuzzy inference system procedures, used very good effect.)

用分步法 计算 耦合非线性薛定谔方程； 主要用于高功率锁模增益光纤激光器的数字模拟； 模拟步骤分四步：光纤损耗传输、色散、非线性、增益； finding 是主程序，其它是函数 (Digital-to-analog simulation steps coupled nonlinear Schrö dinger equation is mainly used for high-power mode-locked gain fiber laser with a fractional step in four steps: the fiber loss transmission dispersion nonlinear gain finding is the main program, other functions)

this is buck inverter with pwm control

UPFC with series and shunt FACTS controllers

说明：  计算时变重力场变化的程序，通过此程序可以计算地球质量变化等等。(Changes in time-varying gravity field calculation program, this program can be calculated by changes in Earth' s mass and so on.)

用matalb程序来实现求一个连通图的最小生成树(matalb procedures used to achieve a graph for the minimum spanning tree)

OFDM系统程序，实现简单的基带OFDM系统(ofdm system code，build a simple ofdm system)

用修正协方差法对信号进行频率估计，并通过仿真图形得出该方法的优缺点。(The modified covariance method estimates the signal frequency, and graphics obtained through the simulation of the advantages and disadvantages of the method.)
