Simulink

matlab内容精讲，自己看过了感觉挺好的 推荐学习matlab的同学们可以看看(The matlab content succinctly and have seen a very good feeling the recommended learning matlab classmates can look)

说明：  GA算法的matlab代码实现，包括选择函数和简单的测试问题(GA algorithm matlab code)

本代码为扩展卡尔曼滤波仿真，适合初学者使用学习。(The extended Kalman filter simulation code, suitable for beginners to learn.)

说明：  Adaptive Watermarking

在OFDM系统中，自适应资源分配是很重要的，注水算法是资源分配的经典算法，本程序对注水算法进行了仿真(In OFDM systems, adaptive resource allocation is very important, water resource allocation algorithm is a classic algorithm, the procedure for filling algorithm for the simulation)

复杂网络中的小世界模型，包括nw模型和Sw模型还有求度分布的matlab程序代码。(Complex network of small-world model, including model and Sw model nw still seeking distribution of the matlab program code.)

共轭梯度法是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。(Conjugate gradient method is between the steepest descent method and Newton method between a method that only use the first derivative information, but the steepest descent method to overcome the disadvantage of slow convergence, but also avoids the need to store and calculate Newton Hesse matrix and the shortcomings of the inverse, conjugate gradient method is not only linear equations to solve large-scale one of the most useful, large-scale nonlinear optimization solution is also the most efficient algorithms.)

greedy algorithm in OFDM resource allocation (single user)

spider，很好用的模式识别工具箱，里面有各种分类工具，从有监督学习到无监督学习，从模型选择到参数选择。而且也将各个方法封装成类，使用方便。(spider, good use of pattern recognition toolbox, there are various classification tools, from supervised learning to unsupervised learning, choose Preferences from the model. But also the various methods into a class package, easy to use.)

用二阶自回归（AR2）模型估计信号的瞬时频率(Using second-order autoregressive (AR2) model estimates the instantaneous frequency signal)
