Reshape/reformat packet coefficients into a multivariate data set
The packet coefficients of a nondecimated wavelet packet object are stored internally in an efficient form. This function takes the nondecimated wavelet packets and stores them as a matrix (multivariate data set). Each column in the returned matrix corresponds to an individual packet, each row corresponds to a time index in the original packet or time series.
