Matlab_Ch5

用FFT对信号进行频谱分析，是在MATLAB环境下通过编程实现。(The signal with the FFT spectrum analysis is adopted in the MATLAB programming environment.)

实现了对视频序列的brick分割，使之分割成几个基元。(To achieve a brick split the video sequence, so split into several primitives.)

基于ukf目标追踪，包含sigma采样、ut变换、ukf的m文件和一个简单的追踪实例(Ukf-based target tracking, including sigma sampling, ut transform, ukf m-files and a simple trace instances)

已知任意两点的经度和纬度求两点间的直线距离以及求两个圆交点坐标(Any two points of known latitude and longitude find straight-line distance between two points)

计算混沌序列的分形维数，内附有洛伦兹序列和哈农序列，可以根据自己所需，产生感兴趣的序列，自行添加。(Fractal dimension calculation chaotic sequence, the sequence is enclosed and Hanon Lorentz sequence, can according to their required to produce a sequence of interest, add their own.)

Raptor结果分析，对实验结果的分析，各种不同类型的曲线描点(Raptor performance analyze)

说明：  完整的curvelet变换(2.0)实现(complete curvelet transform (2.0) Implementation)

说明：  基于非负矩阵分解的语音分离方法，matlab实现(NMF-based speech separation method, matlab implementation)

利用保留交叉验证(hold-out)的特征选择，有筛选排序的功能，并最终可以输出对应特征下标。(The use of cross-validation reserved (hold-out) feature selection, there is sort of filtering function, and eventually you can output the corresponding feature subscript.)

说明：  利用EKF实现单站相位差变化率定位，并计算CRLB、画GDOP图。参考文献为《一种快速高精度无源定位方法的研究》(Using EKF to locate the change rate of single station phase difference, calculate CRLB and draw GDOP diagram. References are "Research on a Fast and High Precision Passive Location Method")
