ekf和ukf的程序的对比，主要应用于目标跟踪方面(ekfVSukf s programme ,it s fitted to track traget.)

some notes abou svd in matlab functions

用matlab程序实现生成gold序列，首先生成m序列，然后用两个m序列生成gold序列。(Matlab program generated by gold sequences, the first generation of m sequences, and then the two m sequence generated by gold sequences.)

基于小波的纹理特征，小波四层分解，特征向量含有均值、标准差、空间频率等，共13*4个特征。(Based on texture feature of wavelet, wavelet decomposition, four layers of characteristic vector containing the mean, standard deviation, such as spatial frequency, a total of 13* 4 characteristics.)

一个自己写的节点导纳矩阵生成程序，不同的小程序完成不同的功能(A self - written node admittance matrix generation procedures)

基于FPGA的增量式PID设计方法，Matlab、Simulink， Xilinx Block set(Incremental PID FPGA-based design methodology)

分形差值函数是由迭代函数系统IFS实现的，通过离散的数据点构成分形插值函数，证明分形插值函数是这个IFS唯一吸引子。利用MATLAB矩阵运算，实现数据点的分形差值拟合。该算法简介直观。(The fractal difference function is implemented by the IFS fractal interpolation function through the data points of the discrete prove fractal interpolation function only attractor of the IFS. Fractal difference fitting using MATLAB matrix operations, the data points. The algorithms Profile intuitive.)

该函数给出无限大障板上圆形活塞声源辐射的声场随时间分布状态图，主要包括：声源辐射随传播时间变化的声场二维分布图和随时间变化的动画(This function simply-supported boundary conditions given on circular piston the sound field radiation over time distribution state figure, mainly including: sound radiation to the propagation of 2 d time change acoustic field distribution and change over time the animation )

说明：  求瞬时频率必不可少，MATLAB系统不自带的，下载后放在MATLAB到toolbox，然后在EMD文件夹下，更新MATLAB路径即可。运行emd即可出现频谱分析图。(It is necessary to find the instantaneous frequency. The MATLAB system does not come with it. After downloading, it is placed in the MATLAB to toolbox. Then, under the EMD folder, the MATLAB path can be updated. The spectrum analysis diagram can appear when EMD is run.)
