利用ＶＣ＋＋与ＭＡＴＬＡＢ编程 希望多交流 也希望资源共享(VC++ and MATLAB programming hope that more exchanges also hope that the sharing of resources)

PQ分解方法潮流计算，自己编写的简单的电力系统潮流计算MATLAB语言(PQ decomposition method flow calculation, I have written a simple power flow calculation MATLAB language)

运用MATLAB程序计算大气空气质量预测预报，运用前一天的气象数据预测未来情景的空气质量。例子给出了输入文件和源程序。(Using MATLAB program to calculate the Air Quality forecast, the day before the use of meteorological data to predict future scenarios of air quality. Examples given in the input file and the source.)

此代码利用高斯牛顿迭代法，对非线性函数进行参数辨识。可以对传递函数通过阶跃响应实验得到的数据进行迭代获得传递函数的参数(The code uses the Gauss-Newton iteration method to identify the parameters of the non-linear function. The parameters of the transfer function can be obtained by iterating the data obtained from the step response experiment of the transfer function.)
