matlab 人工模拟股市系统 对股票感兴趣的朋友可以下载来玩一玩 我试过了 挺不错的。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。(matlab artificial stock market system)

matlab 与VC混合编程 PDF格式 刘维编著 还算清晰，有兴趣的朋友下载下来看看 03(matlab Programming PDF format mixed with VC Liu Wei edited fairly clear, interested to see friends downloaded 03)

加对地支路、非标准变比、稀疏矩阵的潮流计算(Power flow calculation)

4 16 64 QAM plots for simulated and theoretical results for OFDM system with addition of Cyclic prefix and a zero-Forcing equalizer.

用最小二乘法进行预测控制的程序，大家可以用来参考下。(Least square method to predict the control procedures, we can be used to refer to the following.)

极大似法编的系统辨识malab源码，这是基于概率的方法，可以直接拿来作为极大四然的程序短，应用于各种极大四然的实例(Maximum method of system identification malab source)

则卡尔曼滤波的算法流程为： 1.计算预估计协方差矩阵2.计算卡尔曼增益矩阵3.更新估计4.计算更新后估计协防差矩阵(The Kalman filter algorithm processes as follows: 1. Calculate pre-estimate covariance matrix 2 calculate the Kalman gain matrix 3 updated estimate calculated after 4 update estimated defend difference matrix)

这个代码的主要作用是练习用的，可以用它来练习，然后得到提高(The code is based on Practice，so we can use it to make some improvement and maybe it can realize some new functions)

该程序的主要功能是对心音信号进行AR功率谱分析，同时带有去噪功能。(The program' s main function is to heart sound signals AR power spectrum analysis, and with denoising function.)

给定一幅图像，计算图像中谷物的颗粒数，然后使用Matlab进行仿真(Computer the count of the grain in the given image, then uesing matlab to simulate.)
