W.info {fields} | R Documentation |
Functions for finding various indices and sizes of different parts of a 1-d multiresolution and converting to a sequential index.
W.info(m = 128, cut.min = 4) W.i2s(ind, m, cut.min) W.s2i(i, level, m, cut.min)
m |
Length of series |
cut.min |
Number of scale basis functions (or father wavelets) at the coarsest resolution ) |
ind |
Vector of indices of the basis functions. |
i |
Position of the basis function within its level. |
level |
level of resolution (father wavelets have level==0). |
W.info gives summary information about the multiresolution. W.i2s converts a sequential index for the basis functions into a list with locations and levels. W.s2i is the inverse transformation from a list structure to an integer index.
Return list for W.info
m |
length of series |
cut.min |
cut.min (what else!) |
S |
first and last indices for father wavelets |
H |
a matrix where rows are levels of resolution and columns are the first and last indices for the mother basis functions. |
L |
number of basis funcion in each level of the mother wavelets. |
Lmax |
The number of levels of resolution |
offset |
A matrix where rows are levels of resolution and the columns is the offset index for the beginning of the indices for basis funtion at that resolution level. |
