    吉布斯定轨法。 输入:轨道上任意三个点的位矢(R1,R2,R3); 输出:质点在R2端点时的速度V2;ierr是个判断符号,返回的ierr是零的话,就说明‘R1,R2,R3’共面,如果ierr是1的话说明‘R1,R2,R3’不共面(正常情 况下,要构成轨道的话,‘R1,R2,R3’一定共面 ,即ierr是零,如果ierr是1的话说明输入的‘R1,R2,R3’不共面不能构成轨道。 此函数用于:任意给定三个空间共面的向量,可以确定质点在R2处的速度V2,也就得到了轨道上的一个状态向量(R2,V2),调用前面的函数就可以确定其轨道,及任意时刻的状态。(Gibbs set the track method. Input: track any three points of the bit vector (R1, R2, R3) output: particle at R2 endpoint speed V2, ierr is a judgment symbol, The ierr that is returned is zero, then, it means' of R1, R2,, R3, ' coplanar, if ierr is 1, then description' of R1, R2,, R3, ' not a total surface (under normal circumstances, you want to constitute a track, then,' of R1, R2, R3, ' a certain total surface, ierr is zero, if ierr is an instructions to enter the words ' of R1, R2, R3' coplanarity can not constitute a track. This function is used: for any given three space vector of the surface, can determine the particle at the speed V2, R2 also track a state vector (R2, V2), call the previous function can determine its orbit, and at any time of the state.)

    这是第一版的AsymPDC工具包。用来处理PDC,gPDC和iPDC有关内容。运行环境为Matlab,并且要求至少Matlab中预装了3个工具箱:控制系统,信号处理和统计工具箱。(This is the first public release of AsympPDC package. It deals with the asymptotic statistics for PDC, gPDC and iPDC. AsympPDC runs under Matlab and is a practically self-contained except for requires routines from three Matlab toolboxes: Control System, Signal Processing, and Statistical. It is not extensively tested yet. It was partially tested under Windows, Macintosh and Linux environments with Matlab version 7.0 and higher. Please report any incompatibility to ksameshi[at]usp.br or baccala[at]lcs.poli.usp.br. Additionally for cosmetic purposes, the pdc_xplot routine uses several Matlab users contributed codes: subplot2.m (modified old version of supbplot to control spacing between subplots), shadedplot.m (developed by Dave Van Tol), suplabel.m (for label and title plotting in subplot figures, by Ben Barrowes), suptitle.m (contributed by Drea Thomas, for adding title above all subplots), and tilefigs.m (for tiling figures for simultaneous visualization, by Charles Plum))
