economic load dispatch by quadratic programming

经典的利用matlab做的卡尔曼滤波。代码可以运行。读者可以和PF对比；(Classic Kalman filter using matlab to do. Code can run. Readers can compare and PF )

MATLAB爬虫程序，获取指定时间段的所有上市公司公告文本。(A MATLAB spider can fetch the published texts by A-stock companies in certain period.)

这个系统是基于matlab的双闭环直流调速系统，控制器使用了单片机，性能达到了设计要求。(The system is based on the matlab dual closed loop DC system, the controller uses single chip, the performance meets the design requirements.)

matlab 三维显示。所有代码都有。可以显示三维网格。(three-dimensional display matlab. Have all the code. Can display three-dimensional grid.)

利用自适应陷波器对引入单频干扰的原始正弦信号进行恢复(The use of adaptive notch filter for the introduction of single-frequency interference for the restoration of the original sinusoidal signal)

说明：  卡尔曼滤波器是用前一个估计值和最近一个观察数据估计信号的值，他是用状态方程和递推的方法进行估计，本例用来追踪一个5阶的FIR不确定的滤波器系数。(Kalman filter is to use the previous estimate and the most recent observation data to estimate the value of the signal, he is using the state equation and recursive estimation methods, in this case is used to track a 5-order FIR filter coefficients of uncertainty.)

通过rls进行时延估计，不仅收敛速度快，而且在较低信噪比条件下，仍能够得到时延估计值(rlstde)

说明：  络检波法，也可以用同步解调法，现在我们来使用同步解调法，即将已调信号和一个与载波信号同频率的信号相乘，在通过一个理想低通滤波器就可以得到原始信号(Envelope detection method, you can also use synchronous demodulation method, and now we use synchronous demodulation method, is about modulated signal and a signal is multiplied with the same frequency of the carrier signal, through an ideal low-pass filter can get the original signal)
