粒子群做非线性模型的参数估计，已检测很好用(nonlinear parameter estimation)

MATLAB二维绘图，通过TXT文件读取数据(MATLAB 2D plot read data TXT)

The smooth particle hydrodynamics (SPH), the diffuse element method (DEM), the element-free Galerkin method (EFGM), the reproducing kernel particle method (RKPM), the moving-particle semi-implicit method (MPS) are among others. However, it seems that these meshless methods have not succeeded in replacing the FEM analysis completely, while they show excellent performance in several special fields.

说明：  有用的matlab遗传算法整定模糊pid论文(Useful matlab genetic algorithm-tuning fuzzy pid Papers)

some tutorials and books of matlab

说明：  一种基于信息熵的Matlab端点检测算法，抗噪性能比较好(Matlab based on information entropy of the endpoint detection algorithm, better anti-noise performance)

此为利用小波来进行去噪处理的几种程序举例，期中包括wnoise 函数测试去噪、图像噪声处理、图像用户界面（GUI）的压缩和去噪声处理三方面。(This is to use wavelet denoising examples of several programs, including wnoise function test period denoising, image noise processing, graphical user interface (GUI) of the compression and to deal with three aspects of noise.)

多普勒测速：自相关频率估计，估计误差等仿真(about Doppler velocimetry: from the relevant frequency estimation, estimation error and other simulation )

简化的OFDM系统仿真，其中暂未考虑扰码和卷积码，物理层参数采用802.11a参数，1个长训练符号与6个OFDM数据符号构成1帧，信道为单径rayleigh衰落信道，其中最大多普勒频移为100Hz，信噪比0-30dB，调制方式为QPSK和16-QAM。(Simplified OFDM system simulation, which yet consider scrambling and convolution codes, physical layer parameters using 802.11a parameters, a long training symbols and six OFDM data symbols constitute a channel for single-path rayleigh fading channel, one of the largest Doppler shift is 100Hz, the SNR 0-30dB, the modulation scheme is QPSK and 16-QAM.)

he modeling equation of this system is MD2X+bDX+kX = F The transfer function between the displacement X(s) and the input F(s) then becomes X(s) / F(s) = 1 / (Ms2 + bs +k)
