用有理多项式做Chebyshev逼近的一种直接方法的matlab程序(Direct Method for Chebyshev Approximation by Rational Functions)

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)

Matlab命令大全，可以找到几乎全部的Matlab命令，是新手学习Matlab不可缺少的材料(Matlab command Daquan, can be found in almost all of the Matlab command, a novice to learn the material indispensable for Matlab)

FFT变换后，求取信号的振幅谱和相位谱，(Calculating the amplitude spectrum and phase signal spectrum)

抑制饱和PID控制器，已经进行了改进。可以将其改进为PI调节器(Inhibition of saturated PID controller has been improved. Can be improved for the PI regulator)

传统的DOA估计算法，如MUSIC、ESPRIT算法，都是在假设信号没有相干的情况下求解的，一旦信源信号具有相干性，估计性能会急速下降，所以提出了空间平滑的算法，解决相干信号的波达估计！(The traditional DOA algorithms, such as MUSIC, ESPRIT algorithm, is under the assumption that the signal is not coherent case solving, once the source signal with coherence, estimation performance will fall, so put forward spatial smoothing algorithm, to solve the coherent signal estimation of direction of arrival!)

资料为matlab PLL_ADC_DDS建模资料，值得参考。。。(nformation for matlab PLL_ADC_DDS modeling data, worthy of reference.....)

matlab里FFT变换时的频移程序，自动将FFT变化后的数据移到零频两边，方便好用(FFT transform in matlab frequency shift when the process changes automatically after the FFT to the zero-frequency data on both sides, easy-to-use)
