说明：  一个有关matlab解决最小二乘法函数lsqcurvefit的简要介绍，网上找的，分享了。。。(Matlab solve a least squares lsqcurvefit function of a brief introduction, on-line to find and share.)

里面包含五个有关matlab的学习的资料，特别适合初学者使用。(a very good learning material of matlab learning.)

Gravitational search algorithm document had been sheared

这是一个EEMD 分解的程序，可以用在故障诊断中，可以运行(This is a EEMD decomposition program that can be used in fault diagnosis, you can run)

计算以为曲线序列的分数维，可以用于提取分形特征(Calculated that the fractal dimension of the curve sequence can be used to extract fractal characteristics)

在详细介绍各种命令的同时,向读者介绍了MATLAB在高等数学,线性代数,图形图像处理等方面的应用和外部接口.(In detail the various commands at the same time, introduced to readers MATLAB in higher mathematics, linear algebra, graphics, image processing and other applications and external interfaces.)

一个非常简易的均线策略，仅作展示用，高手绕行。 5日均线上穿20日均线，做多1手；5日均线下穿20日均线，做空1手； 其中这里上穿、下穿如下定义： 上穿定义：MA5当天大于MA20，前一天MA5位于MA20之下 下穿定义：MA5当天小于于MA20，前一天MA5位于MA20之上 测试数据：IF1112 （2011/5/3-2011/12/8）每日收盘价。 初始资金 50万(a sample back testing matlab code based on ma)

代码为实现了信道CLARKE模型的仿真代码(Code for the implementation of channel simulation code CLARKE)

说明：  这是学习matlab视频仿真很好的一个工具，通过它，朋友们可以学到很多知识。能够快速提高建模仿真能力(This is a very good learning matlab video simulation of a tool through which friends can learn a lot of knowledge. To rapidly enhance the capacity of modeling and simulation)
