These Simulink blocks contain transfer functions that model the pressure and flow transients for axisymmetric 2D viscous flow of a compressible fluid in a straight rigid circular cross section pipelines. Three models are available: (1) pressures at the ends (2) flow rates at the ends (3) pressure at one end and flow rate at the other Filtering is incorporated to reduce numerical oscillation (gibbs phenomenon). See J. Dyn. Systems, Meas. & Control vol 122 (2000) pp. 153-162.

优点:1.对于信噪比高的信号滤波效果好; % 2.对于边沿的保护强过阈值滤波,不会产生阈值滤波情况下的过于平滑与gibbs现象。 %缺点:1.由于对边沿信号没做任何处理,所以边沿可能会有脉冲噪声保留下来; % 2.计算相关系数中,如果计算出来的小波系数点位置偏差大,则相关系数计算受影响; % 3.需要迭代运算,迭代的噪声能量阈值选取很重要,这里以开始段无信号处估计噪声; % 4.需要迭代运算,所以运算量比阈值法大; % 5.受分解层次影响,在大尺度上小波系数点位置偏差更大,相关系数计算不准确。 %需要具体调整的地方:1.分解的尺度;

The package includes 3 Matlab-interfaces to the c-code: 1. inference.m An interface to the full inference package, includes several methods for approximate inference: Loopy Belief Propagation, Generalized Belief Propagation, Mean-Field approximation, and 4 monte-carlo sampling methods (Metropolis, gibbs, Wolff, Swendsen-Wang). Use "help inference" from Matlab to see all options for usage. 2. gbp_preprocess.m and gbp.m These 2 interfaces split Generalized Belief Propagation into the pre-process stage (gbp_preprocess.m) and the inference stage (gbp.m), so the user may use only one of them, or changing some parameters in between. Use "help gbp_preprocess" and "help gbp" from Matlab. 3. simulatedAnnealing.m An interface to the simulated-annealing c-code. This code uses Metropolis sampling method, the same one used for inference. Use "help simulatedAnnealing" from Matlab.

这是一本讲述matlab中涉及到统计方面的知道书籍,特别是对采样,gibbs采样,都有很好的示例。
