在系统辨识中，关键的是系统建模这里提出了多种方法(In system identification, system modeling is the key to a variety of methods presented here)

This is the second part of Noonegative Matrix Factorization

QAM 调制完整代码，MATLAB实现，通俗易懂，适合初学者学习参考。(QAM Modem Demo)

说明：  关于MATLAB DVB的 有兴趣的可以看看，主要还是在DVB中OFDM的仿真 ！说明是英文的哦！(On the MATLAB DVB interested can look at, mainly in DVB in OFDM simulation! Description is in English Oh!)

布丰投针的函数，蒙特卡洛方法求解pi的近似值(Buffon cast pin function Monte Carlo method for solving an approximation of pi)

基于时域有限差分法的电磁波二维传导方程，MATLAB编写，可作为二维正演模拟，也可作为MATLAB的教学演示。(FDTD method based on the electromagnetic two-dimensional conduction equation, MATLAB prepared, can be used as two-dimensional forward modeling, but also as a teaching demonstration of MATLAB.)

We see from the graphs , that as the number of samples increased, the estimation gets better. As now for increased number of samples , variance of estimators are reduced. So, we get better estimation.

说明：  matlab代码仿真海浪模拟模型，matlab语言(Matlab code simulation ocean wave simulation model, MATLAB language)
