描述----------Description----------
Converts flattened wavelet packet node indices to corresponding level and oscillation
平坦的小波包节点索引转换到相应的水平和振荡
用法----------Usage----------
wavPacketIndices(x, check.basis=TRUE)
参数----------Arguments----------
参数:x
a vector of flattened wavelet packet node indices.
一个向量小波包节点索引被夷为平地。
参数:check.basis
a logical value. If TRUE, the set of specified indices is checked to ensure that the corresponding wavelet packet nodes form a legitimate basis by ensuring that (i) the union of all frequency ranges corresponding to the packet crystals span the normalized frequencies [0,1/2] and (ii) the normalized frequency ranges for all nodes do not overlap. Default: TRUE.
一个逻辑值。如果TRUE,组指定的索引进行检查以确保相应的小波包节点,形成一个合法的基础上,确保(i)本联盟的所有频率范围对应的数据包晶体跨越的归一化频率[0, 1/2]和(ⅱ)对所有节点的归一化的频率范围不重叠。默认值:TRUE。

详细信息----------Details----------
In general, wavelet packet crystals can be arranged in the so-called natural order ala W(0,0) , W(1,0), W(1,1), W(2,0), W(2,1), W(2,2), W(2,3), ... , W(J,0), ..., W(J, NJ) where J is the number of decomposition levels and NJ. By definition, W(0,0) is the original time series. A given crystal is identified in the W(j,n) form above or by a flattened index. For example, the DWPT crystal in level 2 at oscillation index 1 is identified either by j,n=2,1 or by its flattened index 4 (with zero based indexing, 4 represents the fifth crystal of the wavelet packet transform in natural order). This function converts such flattened wavelet packet indices to the W(j,n) form.
在一般情况下,小波包晶体可以安排在所谓的自然顺序阿拉W(0,0) , W(1,0), W(1,1), W(2,0), W(2,1), W(2,2), W(2,3), ... , W(J,0), ..., W(J, NJ)其中J是层层分解和NJ。根据定义,W(0,0)是原来的时间序列。在W(j,n)形式或扁平指数确定一个给定的晶体。例如,DWPT的水晶被确定在2级涛动指数1 J,N = 2,1或扁平指数(以零为基础的索引,4表示第五晶体的小波包变换的自然顺序) 。此功能将展开的小波包的指数W(j,n)形式。
值----------Value----------
a list of flat, level, and osc vectors containing the flattened, decomposition level, and oscillation indices, respectively, corresponding to the input.
的列表flat,level,和osc向量的平坦化,分解的水平,和振荡指数,分别对应于输入的。
