奇异值分解降噪技术，对各种信号进行处理，使用先进的MATLAB程序进行分解处理，达到理想的效果(SVD noise reduction on various signal processing, the use of advanced decomposition MATLAB processing procedures to achieve the desired results)

四元数matlab代码中的基本程序，方便理解四元数的构成(Quaternion matlab code of the basic procedures to facilitate the understanding of the composition of quaternion)

此小程序用于构造小波基 并采用双尺度方程求解小波基函数(this small procedure for the construction of small Porgy and double standards equation wavelet function)

根据系统的输入和输出，辨识系统的的传递函数。该系统为6阶系统，通过降阶降为2阶后，加入状态反馈和状态观测器，调整参数使2阶系统稳定，最后用于控制原6阶系统。阶跃响应和bode图效果都不错。(Based on the input and output of the system, the transfer function of the system is identified. The system is a 6 order system. After the order is reduced to 2 order, the system is added with the state feedback and the state observer, which adjusts the parameters to make the 2 order system stable. Finally, it is used to control the original 6 order system. Step response and Bode figure results are good.)

粒子群算法OptSwarm记录每个粒子的历史最优解（粒子历史最好的适应度）以及全部粒子搜索到的全局最优解。用Wg代表全局最优解，W.,1代表每个粒子的历史最优解。粒子群初始化阶段表OptSwarm的前N行与表ParSwarm中的相同，而Wg的值为表ParSwarm中适应度值的最大值对应的行。(Particle swarm algorithm OptSwarm record the history of each particle the optimal solution (particles history best fitness), and all the particles of the search to the global optimal solution. Use Wg represents the global optimal solution, w., 1 representative of each particle history to the solution. Particle swarm initial stage OptSwarm table before the line and the table ParSwarm N is same, and the value of the ParSwarm Wg for tables in the maximum fitness value corresponding line. )

Gamma Intensity Correction matlab code

这个matlab程序主要介绍的而是OFDM调制过程，主要设置了符号数，载波数，循环前缀大小，对信号进行了IFFT变换，串并转换等。(The matlab program introduces the OFDM modulation process but the main set of symbols, the number of carriers, cyclic prefix size, the signal of the IFFT transform, string and conversion)

For interplating the image using bi liner interpolation.

说明：  时间序列分析中参数估计方面的实现,在matlab环境下实现的代码(parameter estimation)
