国外分享的采用正交匹配追踪算法MATLAB环境源码

用于非线性时间序列分析的软件包。可用于计算：时间延迟重构，分形维数，互信息，Lyapunov指数，替代数据集，最近临点统计，回归时间，庞加莱截面，非线性预测(TSTOOL is a matlab software package for nonlinear time series analysis. TSTOOL can be used for computing: Time-delay reconstruction, Lyapunov exponents, Fractal dimensions, Mutual information, Surrogate data tests, Nearest neighbor statistics, Return times, Poincare sections, Nonlinear prediction. )

局域均值分解的程序，此为经验模态分解方法的另一种改进，此方法能够减小端点效应的影响，但是模态混叠问题还是没有得到完全抑制(Local mean decomposition process, this is the empirical mode decomposition method is another improvement, this method can reduce the effect of the endpoint, but the modal aliasing problem has still not been completely suppressed)

Pisarenko谐波分解算法,真的是一个好程序，实现用SDRAM运行nios，同时用SRAM保存摄像头数据，比较了软阈值，硬阈值及当今各种阈值计算方法,旋转机械二维全息谱计算的实用例程，最终的权值矩阵就是滤波器的系数。
