S (cell): The scattering representation to be formatted.
fmt (string): The desired format. Can be either 'raw',
'order_table' or 'table' (default 'table').
out: The scattering representation in the desired format (see below).
meta (struct): Properties of the scattering nodes in out.
Three different formats are available for the scattering transform:
'raw': Does nothing, just return S. The meta structure is empty.
'order_table': For each order, creates a table of scattering
coefficients with scattering index running along the first dimen-
sion, time/space along the second, and signal index along the
third. The out variable is then a cell array of tables, while
the meta variable is a cell array of meta structures, each
corresponding to the meta structure for the given order.
'table': Same as 'order_table', but with the tables for each order
concatenated into one table, which is returned as out. Note that
this requires that each order is of the same resolution, that is
that the lowpass filter phi of each filter bank is of the same
bandwidth. The meta variable is one meta structure formed by con-
catenating the meta structure of each order and filling out with
-1 where necessary (the j field, for example).
