Function DISPLAY_SLICE
Package
display
Short description
Display a scattering transform slice
Usage
[sc1, sc2] = DISPLAY_SLICE(S, t, scale, options)
Input
S (cell): A scattering transform.
t (int): The time index for which coefficients are to be displayed.
scale (int, optional): The j-prefix of the coefficients to be displayed
(default []).
options (struct, optional): Different options for the display. Currently
unused.
Output
sc1 (numeric): The coefficients satisfying j = [scale j_m].
sc2 (numeric): The coefficients satisfying j = [scale j_m j_(m+1)].
Description
The function displays scattering coefficients of order m and m+1, where
m = length(scale)-1, whose prefix is given by scale. For the coefficients
of order m, there only exists one degree of freedom, the last scale j_m,
so these are displayed in a vertical image to the left. The coefficients
of order m+1 exhibit two degrees of freedom, j_m and j_(m+1), and so is
plotted as a two-dimensional image to the right, with j_m running along
the same axis as the mth-order coefficients (vertically) and j_m
running along the horizontal axis. Note that scales run from top to bot-
om and right to left so that frequencies run from bottom to top and
left to right.
The most typical usage leaves scale equal to the empty prefix, giving a
display of first-order coefficients to the left and second-order coef-
ficients to the right.
