Natural Gas Prediction Using The Group Method of Data Handling

A Matlab object that acts just like a matrix but represents a linear operator as a function.

说明：  升余弦脉冲的设计实例，升余弦脉冲是一种具有零ISI的脉冲波形，此程序用来产生升余弦脉冲。(Raised cosine pulse design example, raised cosine pulse is a pulse waveform with zero ISI, the program used to generate raised cosine pulses.)

绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

说明：  本论文介绍了几种用于高动态和弱信号环境下的GPS接收机捕获算法，并对其性能进行了分析(This dissertation develops Global Positioning System receiver algorithms for high dynamic and weak signal .)

小波阈值降噪的例程，可以选择多种原始信号及多种阈值方式。(Wavelet threshold noise reduction routine, you can choose a variety of the original signal and multi-threshold approach.)

这个例子里，我们将独立(白噪声)样本通过有5dB通带纹波的切比雪夫滤波器。 试估计滤波器输出端的PSD。实现这一估计的MATLAB程序如下: (This example, we will be independent (white noise) samples through a 5dB passband ripple Chebyshev filter. Estimate the filter output PSD. MATLAB program to achieve this estimate is as follows:)
