%****s* Structures/wtf_s
%
% NAME
%   wtf_s -- wavelet transform filter struct.
%
% DESCRIPTION
%  wtf_s struct has fields:
%   * g         -- scaling (low-pass) filter coefficients (vector).
%   * h         -- wavelet (high-pass) filter coefficients (vector).
%   * L         -- filter length (= number of coefficients) (integer).
%   * Name      -- name of wavelet filter (character string).
%   * Class     -- class of wavelet filters (character string).
%   * Transform -- name of transform (character string).
%
%  Possible values for transform are:  DWT, MODWT.

%****s* Structures/w_att_s
%
% NAME
%   w_att_s -- wavelet transform attributes struct.
%
% DESCRIPTION
%  w_att_s struct has fields:
%   * Transform  -- name of transform ('MODWT') (string).
%   * WTF        -- name of wavelet transform filter or a wtf_s struct (string or struct).
%   * NX         -- number of observations in original series (= length(X)) (integer).
%   * NW         -- number of wavelet coefficients (integer).
%   * J0         -- number of levels of partial decompsition (integer).
%   * NChan      -- number of channels in a multivariate dataset (integer).
%   * Boundary   -- boundary conditions applied (string).
%   * Aligned    -- Boolean flag indicating whether coefficients are aligned
%                   with original series (1 = true) or not (0 = false) (boolean).
%   * RetrainVJ -- Boolean flag indicating whether VJ scaling coefficients at all 
%                   levels have been retained (1= true) or not (0 = false) (boolean).
