Details
详细信息----------Details----------
Time-ordered non-decimated transform coefficients when raw are not in exact time alignment due to the phase of the underlying wavelet. This function returns the shifts that are necessary to apply to each resolution level in the transform to bring back each set of time-ordered coefficients into time alignment. Note that the shifts returned are approximate shifts which work for any Daubechies wavelet. More accurate shifts can be computed using detailed knowledge of the particular wavelet used.
时间排序非抽取的变换系数时，原料是不是在确切的时间对准由于底层小波相位。这个函数返回的转变是必要的适用于每个分辨率级别的转换，使每个组的时间顺序到时间校准系数。需要注意的是返回的转变是近似的变化，Daubechies小波的任何工作。使用特别小波的详细知识，可以计算更准确的变化。
Each shift is "to the left". I.e. higher indexed coefficients should take the place of lower-indexed coefficients. Periodic boundaries are assumed.
每个班次是“左”。即较高的索引的系数应该采取较低的索引的系数的地方。周期边界的假定。
This realignment is mentioned in Walden and Contreras Cristan, (1997) and Nason, Sapatinas and Sawczenko, (1998).
这种调整Walden和孔特雷拉斯Cristan，（1997）和利晨，Sapatinas和Sawczenko的，（1998年）中提到的。
值----------Value----------
A vector containing the shifts that need to be applied to each scale level to return them to the correct time alignment.
There are J entries in the vector. The first entry corresponds to the shift required for the finest level coefficients (i.e. level J-1) and the last entry corresponds to the coarsest level (i.e. level 0). Entry j corresponds to the shift required for scale level J-j.
有J向量中的条目。的第一个条目对应于换档所需的最优秀的水平系数（即水平J-1）和最后一个条目对应于最粗糙的水平（即电平0）。条目j对应于所需的级级别J-j换档。

实例----------Examples----------
#[]
# Let's see how the resolution levels have to be shifted [让我们来看看如何转移的分辨率水平有]
#[]
compgrot(4, filter.number=10, family="DaubExPhase")
#[1] 2 6 15 31[[1] 2 6 15 31]
#[]
# In other words. Scale level 3 needs to be shifted two units.[换句话说。级表3级需要要移位的两个单位。]
# Scale level 2 needs to be shifted 6 units[需要将移位级级别2 6个单位]
# Scale level 1 needs to be shifted 15 units[级表第1级需要15个单位转移]
# Scale level 0 needs to be shifted 31 units.[等级水平0需要要移位的31个单位。]
